EG-30 thru 75 Series 4 and PEG-30 thru 65 Series 4 Damper installation Once damper is installed, boiler will not operate without a damper installed. Only dampers listed in the Replacement parts table on page 24 are approved for use on EG and PEG Series 4 standing pilot boilers. Any other vent damper installed could cause severe personal injury or death. The following boiler models must have damper installed: • EG-30 thru EG-65, natural or propane gas. • PEG-30 thru PEG-65, steam, natural gas.
Standing Pilot Boilers — Control Supplement Damper installation continued Minimum clearances to combustibles Provide a minimum of 6” between the vent damper and any combustible material. (Provide a minimum of 46” between jacket top and combustible ceiling.) See EG • PEG • EGH Boiler manual for complete clearance requirements. Installation Do not modify draft hood or damper, or make another connection between draft hood and damper or boiler except as noted below.
EG-30 thru 75 Series 4 and PEG-30 thru 65 Series 4 Checkout procedure 1. See pages 15-18 for “Lighting Instructions”. 2. Raise room thermostat to call for heat. Damper actuator will slowly open damper. 3. When damper is fully open, main gas valve will open and main burners will ignite. Damper must be fully open before main burners light.
