BH-SERIES INSTALLATION, OPERATION AND SERVICE MANUAL SECTION 8: VENTING WARNING combustible wall must have an approved thimble to conform with the above listed codes. Vent pipe must be sloped downward away from the heater 1/2'' (1 cm) for every 20' (6 m). Carbon Monoxide Hazard Heaters installed unvented must be interlocked with sufficient building exhaust. Heaters must be installed according to the installation manual. Failure to follow these instructions can result in death or injury.
SECTION 8: VENTING 8.2 Unvented Operation Sufficient ventilation must be provided in the amount of 4 cfm per 1000 Btu/h firing rate (United States); 3 cfm per 1000 Btu/h firing rate (Canada). Use of optional outside combustion air is not recommended with unvented heaters. If exhaust fans are used to supply ventilation air, an interlock switch must be used to prevent the heater from coming on when the fans are off. This may be done using a pressure switch.

BH-SERIES INSTALLATION, OPERATION AND SERVICE MANUAL 8.10 Common Vertical Venting Requirements: • Maximum of four heaters can be commonly vented through the roof. • Heaters must be of the same BTU output. • Heaters must be controlled by a common thermostat. • Connections to a common stack must be positioned to avoid direct opposition between streams of combustion gases.
SECTION 8: VENTING 8.11 Outside Combustion Air Supply IMPORTANT: If the building has a slight negative pressure or corrosive contaminants, such as halogenated hydrocarbons, are present in the air, an outside combustion air supply to the heater is required. Seal all combustion air pipe joints. 8.11.1 Length Requirements Follow the constraints listed on Page 35, Section 8.6. Use of optional outside combustion air is not recommended with unvented heaters.

SECTION 9: GAS PIPING SECTION 9: GAS PIPING WARNING Fire Hazard Tighten gas hose fittings to connect gas supply according to Figure 23. Gas hose can crack when twisted. Gas hose moves during normal operation. Use only 36" (91 cm) long connector of 1/2" or 3/4" nominal ID. Connector supplied with heater for U.S. models (not with Canadian models). Failure to follow these instructions can result in death, injury or property damage. WARNING Explosion Hazard Install the gas hose as shown in Figure 23.
BH-SERIES INSTALLATION, OPERATION AND SERVICE MANUAL FIGURE 23: Gas Connection with Flexible Gas Hose CORRECT POSITIONS CAUTION Product Damage Hazard Shut-Off Valve (included with gas hose) must be parallel to burner gas inlet. The 3" (8 cm) displacement shown is for the cold condition. This displacement may reduce when the system is fired. Hold gas nipple securely with pipe wrench when attaching gas hose. Failure to follow these instructions can result in product damage.
SECTION 10: WIRING SECTION 10: WIRING Heaters can be controlled using several methods. Normally thermostats are used to control the heaters but they can also be controlled by an energy management system. Section 10.1 illustrates the connection for heaters controlled by a line voltage thermostat. For heaters on a low voltage thermostat, See Page 44, Section 10.2.

BH-SERIES INSTALLATION, OPERATION AND SERVICE MANUAL For best performance, the gas, electrical, thermostat connections, tubing, venting, suspensions and overall heater condition should be inspected thoroughly. NOTE: Gas flow and burner ignition are among the first things that should be inspected. Please see Page 49, Section 11.5 for suggested items to inspect.
SECTION 11: OPERATION AND MAINTENANCE 11.5 Maintenance Checklist Installation Code and Annual Inspections: All installation and service of ROBERTS GORDON® equipment must be performed by a contractor qualified in the installation and service of equipment sold and supplied by Roberts-Gordon and conform to all requirements set forth in the ROBERTS GORDON® manuals and all applicable governmental authorities pertaining to the installation, service and operation of the equipment.
BH-SERIES INSTALLATION, OPERATION AND SERVICE MANUAL Burner Cup and Orifice Clear of obstructions (even spider webs will cause problems). Electrode Carefully remove any dust and debris from the burner. Replace if there are cracked ceramics, excessive carbon residue, or erosion of the electrode. Thermostat Suspension Points The electrode gap should be 1/8" (3.2 mm). There should be no exposed wire or damage to the thermostat. See Page 43, Section 10. Make sure the heater is hanging securely.
SECTION 12: TROUBLESHOOTING SECTION 12: TROUBLESHOOTING DANGER Electrical Shock Hazard Disconnect electric before service or maintenance. Heater must be connected to a properly grounded electrical source. Failure to follow these instructions can result in death or electrical shock. WARNING Fire Hazard Keep all flammable objects, liquids and vapors the minimum required clearances to combustibles away from heater. Explosion Hazard Turn off gas supply to heater before service or maintenance.
52 Is there spark at the igniter? YES Turn up thermostat. Does the blower turn on? NO NO Check wiring between the power cord, blower motor and transformer. NO YES YES NO Reconnect transformer wires. Place a jumper wire across the pressure switch. Is there a spark? Replace transformer. Replace ignition module. NO YES Remove the blue and yellow wires from the transformer.
