    CONTROL PANEL INDEXING The exhaust discharges vertically from outside the vent cover. The heater control panel assembly on top of the jacket can be turned to any of six positions for convenient access to the panel as follows: 1. Unbolt and separate the jacket halves. 2.
  • Page 11 The heater is design certified by CSA International for installation on combustible flooring. For installation on car- peting, the heater must be mounted on a metal or wood panel that extends at least three (3) inches beyond the base of the heater. If the heater is installed in a closet or alcove, the entire floor shall be covered by the panel.
  • Page 12 VERTICAL VENTING - NEGATIVE PRESSURE (See Figures 11 and 12) Vent the heater vertically in a negative pressure (positive draft) system in accordance with the National Fuel Gas Code, ANSI Z223.1, and local codes. Type “B” Double- wall vent connector is recommended; however single-wall pipe is allowed by the National Fuel Gas Code in some circumstances.
  • Page 13 6. See Table 4 for height of vent termination above the roof. 7. Do not run the heater vent into a common vent with any other appliance. Fire Hazard. Do not vent the heater directly into a masonry chimney. Installation into a masonry chimney must use a chimney liner and must meet National Fuel Gas Code requirements and all local code requirements.
  • Page 14 4. Install vent pipe so that it can expand and contract freely as the temperature changes. Support the vent pipe according to applicable codes and vent manufac- turer’s instructions. Pipe support must allow the vent pipe free movement out and back, from side to side, or up and down as necessary, without putting a strain on the heater or vent body.

  • Page 16 A manual bypass valve should be installed across the heater when the pump flow exceeds 120 GPM. See instructions below for setting of the manual bypass. Make sure that the outlet plumbing from the heater con- tains no shut-off valves or other flow restrictions that could prevent flow through the heater (except as noted below).
  • Page 17 WATER FLOW RATE Maximum and minimum water flow rates required by the heater are listed below: Table 8: Maximum and Minimum Flow Rate in GPM Model Minimum Flow If the water flow rate to the heater is above 120 GPM, it must be reduced by installing a manual bypass valve (Figure 17).
  • Page 18: Pressure Relief Valve

    WATER PRESSURE SWITCH Hazardous pressure. Do not bypass the Water Pressure Switch or render it inoperable. Switch Settings The water pressure switch turns off the burner if the water flow is interrupted. If the water flow is restricted, the water pressure switch may prevent the burner from firing and cause the “Service System”...
  • Page 19: Checking Combination Gas Control Valve

    To avoid water damage or scalding from operation of the relief valve, install a drain pipe in the outlet of the pressure relief valve that will direct water discharging from the valve to a safe place for disposal. Do not install any reduc- ing couplings or valves in the drain pipe.
  • Page 20: Gas Connections

    GAS CONNECTIONS The heater requires a gas supply of not less than 4” wc and not more than 14” wc. Gas supply pressures outside of this range may result in improper burner operation. A minimum inlet pressure of 4” wc is required to maintain input rating. The gas supply must be installed in accordance with the National Fuel Gas Code, ANSI Z223.1, and all applicable local codes.
  • Page 21 Connect the hot lead of the power supply to the black wire, the neutral lead to the white wire, and the ground wire to the green wire (See Figure 23). A time clock controlling the filter pump should have a low- voltage Fireman’s Switch that switches off the heater at least 15 minutes before shutting off the pump.
  • Page 22 6. Reinstall and bolt up the jacket halves. The fuse for the Fireman’s Switch is 1.25 amp 1-1/4x1/4” fast blow fuse, available locally. MAXIMUM TEMPERATURE SET POINT 1. Unbolt and remove upper jacket halves (see Figure 3, Page 5). 2. Depress clips and remove control board assembly dome (see Figure 9, Page 10).
  • Page 23 Initial Troubleshooting Only qualified, trained service technicians with appropriate test equipment should service the heater. Remember that all parts of the system affect heater operation. Before starting this troubleshooting procedure, make sure that the pump is running correctly, that there are no blockages in the system, that the valves are correctly set and that the time clock is correctly set and is running.
