All gas fired appliances require air to be used for the combustion process. In many buildings today, there is a negative indoor air pressure caused by exhaust fans, etc. If sufficient quantities of combustion air are not available, the heater or another appliance will operate in an inefficient manner, resulting in incomplete combustion which can result in the production of excessive carbon monoxide.
Insufficient combustion air can cause headaches, nausea, dizziness, asphyxiation or death.
If indoor air is to be used for combustion, it must be free of the following substances or the life of the heat exchanger will be adversely affected: chlorine, carbon tetrachloride, cleaning solvent, halogen refrigerants, acids, cements and glues, printing inks, fluorides, paint removers, varnishes, or any other corrosives.
NOTE: The vent is a passageway, vertical or nearly so, used to convey flue gases from an appliance, or its vent connector, to the outside atmosphere. The vent connector is the pipe or duct that connects a fuel-gas burning appliance to a vent or chimney.
Unit heaters must be vented in compliance with all local codes or requirements of the local utility, the current standards of the (American) National Fuel Gas Code, ANSI Z223.1 or (Canada) CSA B149.1 Natural Gas and Propane Installation Code, and the following instructions.
Do not intermix different vent system parts from different manufacturers in the same venting system.
Vent connectors serving Category I and Category II Appliances shall not be connected into any portion of mechanical draft systems operating under positive pressure.
A metal stamped/extruded transition is supplied with this certified unit. It must not be modified or altered and must be installed on the outlet of the induced draft blower assembly prior to the installation of the vent or vent connector. Failure to comply with this requirement will void the certification of the unit by the approval agencies. All joints shall be secured with at least two corrosion resistant screws. All joints must be checked for gas tightness after installation.
The heater and the venting system shall be inspected once a year by a qualified service agency.

The following additional requirements apply when a lined masonry chimney is being used to vent the compact unit / utility heater.
Single appliance venting of a fan assisted unit heater into a tile lined masonry chimney (interior or outside wall) is prohibited. The chimney must first be lined with either type B-1 vent or an insulated single wall flexible vent lining system, sized in accordance with venting tables in the (American) National Fuel Gas Code ANSI Z223.1 or (Canada) CSA B149.1 Natural Gas and Propane Installation Code.
In the event that an existing unit heater is removed from a venting system commonly run with separate gas appliances, the venting system is likely to be too large to properly vent the remaining attached appliances. The following test should be conducted while each appliance is in operation and the other appliances are not in operation, yet remain connected to the common venting system. If the venting system has been installed improperly, the system must be corrected.
NOTE: The MHU series unit/utility heaters use a direct spark ignition system. There is no pilot necessary as the spark lights the main burner as the gas valve is turned on. The direct spark ignition control board emits radio noise during burner ignition. The level of energy may be enough to disturb a logic circuit in a microprocessor controlled thermostat. It is recommended that an isolation relay be used when connecting the unit heater to a microprocessor controlled thermostat. Select circuit protection and wire size according to the unit rating plate. Install a separate disconnect switch (protected by either fuse or circuit breaker) near the unit so that power can be turned off for servicing. Remove electrical junction box cover and connect wiring through knockout on the junction box located on the side of the heater. Refer to heater wiring diagram for connection information. Use 18 gauge wire or larger for line power connections. Make sure to connect line power to wires located in the external electrical junction box behind junction box cover. DO NOT CONNECT LINE POWER TO THERMOSTAT TERMINAL STRIP ON OUTSIDE OF HEATER.
Electrically ground the unit in accordance with local codes or in the absence of local codes, in accordance with the current National Electrical Code (ANSI/NFPA No. 70) in the USA, and in Canada with the current Canadian Electrical Code, Part 1 CSA C22.1
NOTE: Un-insulated ground wire must be wrapped in electrical tape to avoid damage to the electrical system.
Make line voltage connections as shown in figure 6. Connect field wiring as shown on wiring diagram on unit. Also, refer to typical diagram in this manual.
To use the blower for air circulation only, your thermostat must have a "fan only" or fan selection setting. In case your thermostat has this option. an additional wire should be run to the "G" terminal on the thermostat connection block. See wiring schematic in section "Wiring Diagram".
Electric shock hazard. Can cause injury or death. Do not use this heater if any part has been under water. Immediately call a qualified service technician to inspect the furnace and to replace any part of the control system and any gas control which has been under water.
Danger of explosion. Can cause injury or product or property damage. If over-heating occurs or if gas supply fails to shut off, shut off the manual gas valve to the appliance before shutting off electrical supply.
Electric shock hazard. Can cause injury or death. Before attempting to perform any service or maintenance, turn the electrical power to unit OFF at disconnect switch(es). Unit may have multiple power supplies.
Danger of explosion and fire. Can cause injury or product or property damage. You must follow these instructions exactly.
When connecting gas supply lines, the length of the piping run from the meter to the heater must be considered in determining the pipe size to avoid excessive pressure drop. A line pressure of 7" WC (178mm WC) for natural gas should be maintained when sizing the piping.
A line pressure of 13" WC (330mm WC) should be maintained for propane (LP) gas. NOTE: Compounds used on threaded joints or gas piping must be resistant to the actions of Liquefied petroleum gasses.
TO PREVENT HEATER DAMAGE. WHEN USING A PROPANE TANK TO SUPPLY HEATER, A MINIMUM 11"W.C. LOW PRESSURE REGULATOR TO A MAXIMUM 14"W.C. LOW PRESSURE REGULATOR IS REQUIRED. THIS REGULATOR MUST BE INSTALLED BETWEEN THE TANK AND THE HEATER. Regulator not supplied with heater.
For correct sizing of piping, refer to the (American) National Fuel Gas Code ANSI Z223.1, or (Canada) CSA B149.1, National Gas and Propane Installation Code or consult the utility having jurisdiction.
A drip leg should be installed in the vertical pipe run to the unit. In some localities, codes may require that a manual main shutoff valve and union (furnished by installer) be installed external to the unit. Union must be of the ground joint type. A drip leg should be readily accessible to permit cleaning and empting. See figure 7.
NOTE: Leave a min of 4'' clearance to the electrical connections box on the back of the heater to allow for access.
A 1/8" NPT plugged tap shall be installed immediately upstream of the gas supply connection to the heater. The purpose of this is to be able to check for proper gas pressure entering the heater.
DO NOT use matches, candles, flame or other sources of ignition to check for gas leaks.
After gas piping is completed, carefully check all piping connections, (field and factory), for gas leaks. Use a soap solution or other preferred means.
Due to the natural heating cycles and vibration of this unit it is recommended, as part of its annual maintenance, to check these connections for proper tightness and leak-check with a soap solution or other preferred means prior to putting into service.
The heater and its individual shut off valve must be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of 1/2 psig (3.45kPa).
The appliance must be isolated from the gas supply piping system by closing its individual manual gas shutoff valve during any pressure testing of the gas supply system at test pressures equal to or less than 1/2 psig (3.45kPa). See figure 8.
NOTE In case emergency shutdown is required, shut down main gas valve and disconnect main power to unit. These devices should be properly labeled by the installer.
FOR YOUR SAFETY READ BEFORE LIGHTING
BEFORE LIGHTING smell all around the appliance area for gas. Be sure to smell next to the floor because some gas is heavier than air and will settle on the floor.
Use only your hand to move the gas control knob to the on position. Never use tools. Do not use excessive force to switch valve from off to on position. Force or attempted repair may result in a fire or explosion.
MHU 50/80/125 unit heaters are equipped with an automatic spark ignition system. There is no pilot. In case of a safety shutdown, move thermostat switch to OFF, then return the thermostat switch to HEAT position.
Should overheating occur, or the gas supply fail to shut off, shut off the manual gas valve to the appliance before shutting off the electrical supply.
The ignition control board contains a green LED which indicates the following:
TABLE 3 IGNITION CONTROL LED | |
LED | UNIT OPERATION |
Slow Flash | Normal Operation - No call for heat. |
Fast Flash | Normal Operation - Call for heat Current signal at FLAME terminal 0.6 to 1.0 microamps |
2 Flashes | System lockout - failed to detect or sustain flame Current signal at FLAME terminal <0.6 microamps |
3 Flashes | Pressure switch failed closed before CAB is energized or failed open after CAB is energized |
4 Flashes | High limit or rollout switch open |
5 Flashes | Flame sensed and gas valve not energized |
Steady Off | Loss of power/Check 3AMP Fuse on circuit board |
Steady On | Ignition control failure |
*When thermostat is placed in continuous fan mode LED will slowly flash |
The limit control switch is factory set and not field adjustable.
Rotate louver vanes to direct airflow upward, downward, straight, or any combination of these directions. When unit is installed in an inverted position, louvers may be positioned in the same manner.
This pressure switch checks for proper combustion air blower operation before allowing an ignition trial. The switch is factory set and no field adjustment is necessary. If a 3 flash LED occurs Please make sure your venting is not blocked up. Next, remove the end of the pressure switch tubing from the EXHAUST FAN hose barb. There might be an obstruction in the hose barb opening clear out the opening with a thin object that will fit inside the hose barb. Push that through the length of the hose barb PLUS at least another 1/2 inch, into the exhaust fan housing. This will clear out anything stopping the vacuum from engaging the pressure switch.
The flame rollout switch(es) are located on the burner box top, behind the ignition control board. This normally closed switch opens on a temperature rise. Check for adequate combustion air before manually resetting switch.
Units may be fired at full input up to 2000 ft. (610m) above sea level. Above 2000 ft. (610m), manifold pressure must be adjusted on some units. Adjust pressure regulator to pressure shown in table 4 for natural gas and table 5 for LP/propane gas.
