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 not- ed below. This will void CSA certification and will not be covered by
1.Install vent damper horizontally or vertically as shown in vent damper manufacturer’s instructions. Vent damper must be installed so that it serves only one boiler and so damper blade indicator is visible to the user. See Figure 8.
2.Screws or rivets used to secure the vent damper to the draft hood must not interfere with rotation of the damper blade.
3.Install damper harness between damper actuator and knockout in jacket top panel. Use strain relief connectors and locknuts to secure both ends of the damper harness.
Keep wiring harness clear of all hot sur- faces.
4.Read and apply the harness plug warning label (shown above) so that it is visible after installa- tion.
5.Plug damper harness receptacle into damper harness plug.
Bypassing (jumpering) vent damper will cause flue products such as carbon mon- oxide to escape into the house. This will cause severe personal injury or death.
After boiler has operated once, if either end of the harness is disconnected, the system safety shutdown will occur. The boiler will not operate until harness is reconnected.
Effikal damper — Damper hold open switch must be in “Automatic Operation” position for system to operate properly.
