SECTION 1: HEATER SAFETY SECTION 1: HEATER SAFETY Your Safety is Important to Us! This symbol is used throughout the manual to notify you of possible fire, electrical or burn hazards. Please pay special attention when reading and following the warnings in these sections. Installation, service and annual inspection of heater must be done by a contractor qualified in the installation and service of gas-fired heating equipment.
CRV-SERIES INSTALLATION, OPERATION AND SERVICE MANUAL SECTION 2: INSTALLER RESPONSIBILITY The installer is responsible for the following: • To ensure the system is designed in accordance with the parameters of the CRV-Series Design Manual (P/N 127500NA). • To install the heater, as well as the gas and electrical supplies, in accordance with applicable specifications and codes. Roberts-Gordon recommends the installer contact a local Building Inspector or Fire Marshal for guidance.
SECTION 3: CRITICAL CONSIDERATIONS SECTION 3: CRITICAL CONSIDERATIONS 3.1 Required Clearances to Combustibles Clearances are the required distances that combustible objects must be away from the heater to prevent serious fire hazards. Combustibles are materials that may catch fire and include common items such as wood, paper, rubber, fabric, etc. Maintain clearances to combustibles at all times for safety.
CRV-SERIES INSTALLATION, OPERATION AND SERVICE MANUAL NOTE: 1. All dimensions are from the surfaces of all tubes, couplings, elbows, tees and crosses. 2. Clearances B, C and D can be reduced by 50% after 25' (7.5 m) of tubing downstream from where the combustion chamber and the tube connect. * Protective Grille clearances are the same as Standard Reflector.

SECTION 11: GAS PIPING SECTION 11: GAS PIPING There is an expansion of the tube with each firing cycle. This will cause the burner to move with respect to the gas hose. This can cause a gas leak resulting in an unsafe condition if the gas connection is not made in strict accordance with Figure 25. Meter and service must be large enough to handle all the burners being installed plus any other connected load.
CRV-SERIES INSTALLATION, OPERATION AND SERVICE MANUAL SECTION 12: CONTROL METHODS WARNING Electrical Shock Hazard Disconnect electrical power and gas supply before servicing.

SECTION 13: STARTING THE SYSTEM SECTION 13: STARTING THE SYSTEM Start with the main gas valve closed and the electric power off. 13.1 Checking the Gas Line 1. Open the main valve and verify that no gas is flowing through the meter. 2. Purge the line if this was not done following pressure testing with air. 3. Verify that the gas pressure is not above 14'' w.c. (1/2 PSIG). 4. Close the main gas valve. 13.2 Checking the Electrical System 1. See that all temperature setpoints are set below room temperature.

SECTION 14: OPERATION AND MAINTENANCE SECTION 14: OPERATION AND MAINTENANCE The heater is equipped with a direct-spark ignition system. 14.1 Sequence of Operation 1. Turn the thermostat up. When the thermostat calls for heat, the pump will start immediately. After a short period, the burners will begin their ignition sequence. Sparking will begin at the electrodes and the gas valve will be energized 45 seconds later. 2. The flame will be sensed by the flame sensing rod and the electrode is de-energized. 3.
CRV-SERIES INSTALLATION, OPERATION AND SERVICE MANUAL 14.5 Maintenance Checklist WARNING Explosion Hazard Service and annual inspection must be done by a contractor qualified in the installation and service of gas-fired heating equipment or your gas supplier. Turn off gas and electrical supplies before performing service or maintenance.
SECTION 14: OPERATION AND MAINTENANCE Tubes Make sure there are no cracks. Make sure tubes are connected and suspended securely. See Page 15, Figure 12 through Page 17, Section 7.2.1. Make sure there is no dirt, sagging, bending or distortion. Clean or replace as required. Gas Line Check for gas leaks. See Page 41, Figure 25. Combustion Chamber Window Make sure it is clean and free of cracks or holes.
CRV-SERIES INSTALLATION, OPERATION AND SERVICE MANUAL Pump With pump operating, check for excessive vibration or noise. Vibration is usually a sign that the impeller is out of balance. Turn off the system, insure power is shut off and remove the inlet plate. Check the shaft seal and replace it if worn or missing. With the Power off: Check the inlet and outlet of the pump for blockage or excessive soot and clean as necessary. Check boots for cracking or deterioration and replace if necessary.
No Do all the burners ignite smoothly? Yes Yes No After 45 seconds pre-purge period, do the burners light? No Yes Turn up thermostat. Does the pump turn on? START Is the motor hot? Wrong end vent plate may be installed. Make sure plate and burner match. No Is the vacuum setting too high? Refer to control panel list. No Yes Refer to control panel manuals list. Yes Is there power to the zone? Adjust system for proper vacuum at the end vent.
56 No No Yes TROUBLESHOOT ENDS. If problems persist, contact No your ROBERTS GORDON® Independent Distributor. Yes Does the pump shut down after a 2 minute post-purge period? Yes Do burners shut off after the call for heat is satisfied? No Is the flame low? No Is the system leaking water? Yes No Do the burners lockout intermittently? Yes Contact Roberts-Gordon at www.rg-inc.com Make sure that all thermostats or internal sensors are satisfied.
