INTRODUCTION Camus Hydronics proudly introduces its MicoFlame series of water heaters / hydronic boilers. These gas burning appliances are thoughtfully designed for easy operation and maintenance. We are confident that you will come to appreciate the benefits of our product. -
Page 4: Boiler Location
BOILER LOCATION Install this boiler in a clean, dry location with adequate air supply and close to a good vent connection. Do not locate this boiler in an area where it will be subject to freezing. The boiler is suitable for installation on combustible flooring and should be located close to a floor drain in an area where leakage from the boiler or connections will not result in damage to the adjacent area or to lower floors in the structure. -

Page 6: Electrical Wiring
ELECTRICAL WIRING All electrical wiring to the boiler must be electrically bonded to ground in accordance with the requirements of the authority having jurisdiction or, in the absence of such requirements, with the National Electrical Code, ANSI/NFPA 70 or the Canadian Electrical Code Part I, CSA C22.1, Electrical Code. Provide disconnecting means of sufficient rating within sight of the boiler. -
Page 7: Venting
The gas supply line must be of adequate size to prevent undue pressure drop and must never be smaller than the size of the connection on the heater. Sizing based on Table 2 is recommended. Before operating the boiler, the complete gas train and all connections must be tested using soap solution. Table 2 DISTANCE FROM NATURAL GAS METER OR PROPANE SECOND STAGE REGULATOR Input... - Page 8 so they will operate at maximum speed, do not operate a summer exhaust fan. Close fireplace dampers. d) Place in operation the appliance being inspected. Follow the lighting instructions. Adjust thermostat so that appliance operates continuously. e) Test for spillage at the draft control device relief opening after 5 minutes of main burner operation. Use the flame of a match or candle or smoke from a cigarette.
- Page 9 5. CAUTION: When replacing the burner be careful to fully engage the back of the burner box into the retaining slot in the combustion chamber base. Failure to properly locate the burner will result in erratic flame operation with the possibility of delayed ignition on light off. 6.

Page 10: Outdoor Venting
OUTDOOR VENTING When fitted with the factory supplied rain shield and UL approved vent cap, the MicoFlame is self-venting. The following applies to outdoor installations: 1. Use only factory supplied rain shields. 2. Periodically check to ensure that air intake and vent cap are not obstructed. 3. -
Page 11: Filter Kit
The following applies to outdoor air installations: 1. Use only factory supplied air intake terminal. 2. Periodically check to ensure that air intake is not obstructed. 3. Refer to local codes for proper installation and location of vent terminals. Vertical vent terminal must be at least 3 feet above the highest point where it is located above the roof of a building and at least two feet higher than any part of the building within a horizontal distance of ten feet 4. - Page 12 Conventional Venting Multiple appliances may be vented into a conventional chimney. The chimney must be lined with AL29-4C and a single acting barometric damper must be provided for each appliance. Vent diameters are to be increased by one size over the recommended size A qualified professional using a proven vent-sizing program with input of accurate operating parameters must properly calculate sizing of the venting system.

ACCESSORIES WATER FLOW SWITCH (shipped loose) A water flow switch is shipped loose and is to be installed in the outlet piping on all heating boilers and hot water supply boilers. The flow switch is wired in series with the 24VAC safety control circuit. A diagnostic light will be indicated on the control display on a low flow condition. -
Page 14: Freeze Protection
BOILER APPLICATION (HYDRONIC HEATING) In case of boiler (Hydronic heating boiler) application, the return water (supply water) may be more than 115ºF (46ºC), therefore there is no need for a recirculation loop and the primary heat exchanger and CHRM can be piped in parallel. Since the inlet water temperature to CHRM exceeds 115ºF (46ºC) it will not condense fully and therefore the CHRM will not perform to its maximum efficiency capacity. -
Page 15: Piping Of Boiler To System (Fig.4)
Figure 3 When a boiler is connected to heating coils located in air handling units (where they may be exposed to refrigerated air circulation), the boiler piping system shall be equipped with a flow control valve or other automatic means to prevent gravity circulation of chilled water through the boiler. Chilled water in the boiler will create condensate on the boiler tubes, which will collect in the combustion chamber causing corrosion. -
Page 16: Placing Boiler In Operation
Figure 4 If the boiler is installed above radiation level, it must be provided with a low water cutoff device at the time of boiler installation. (Available from factory) To eliminate trapped air, install venting devices at high points in the system as well as in the piping on the suction of the pump and in the piping on the discharge of the boiler. -

Page 32: Removal Of Combustion Chamber Lining
Depending on field conditions air box pressures will have to be adjusted accordingly. Always set the appliance for a CO level in the range of 7.5% to 8.0 % for non-condensing appliances and 8.5% to 9.0% for condensing appliances. For propane fired appliances the setting will be approximately 1.5% higher. A qualified service technician should follow this procedure when burner needs cleaning. -
Page 33: Pilot Burner
17.3 PILOT BURNER Turn the pilot firing valve to off position and allow the appliance to try for ignition. Observe the spark making sure that it is strong and continuous. If the spark is not acceptable the igniter will have to be adjusted. This can be readily accomplished after removing the main burner. -
Page 34: Operation And Service
OPERATION AND SERVICE OPERATION: Before operating the boiler, the entire system must be filled with water, purged of air and checked for leaks. Do not use Stop leak or other boiler compounds. The gas piping must also be leak tested. Any safety devices including low water cutoff, flow switch and high limit used in with this boiler must receive periodic inspection (every six months) to assure proper operation. -
Page 35: Lighting Instructions
SERVICE: Disconnect main power and turn off gas supply before servicing unit. To remove and clean the burner, follow the detailed procedure in section 17 of this manual After the first season of operation inspect the heat exchanger and venting.
