E.Boiler Equipped With Vent Damper. See Figure 26.

1.Open Vent Damper Carton and remove Installation Instructions. Read Installation Instructions thoroughly before proceeding.

CAUTION

Do not use one vent damper to control two or more heating appliances.

2.Vent damper must be same size as draft hood outlet. See Figure 1. Unpack vent damper carefully. Forcing vent damper open or closed may damage gear train and void warranty. Vent damper assembly includes pre-wired connection harness with polarized plug.

3.Mount vent damper assembly on draft hood without modification to either (Refer to instructions packed with vent damper for specific instructions). Vent damper position indicator to be visible to users.

WARNING

Provide adequate clearance for servicing - provide 6” minimum clearance between damper and combustible construction.

F.Install Vent Connector from draft hood or vent damper to chimney. See Figure 27.

1.Do not connect into same leg of chimney serving an open fireplace.

2.Where two or more appliances vent into a common vent, the area of the common vent should at least equal the area of the largest vent plus 50 % of the area of the additional vents. Do not connect the vent of this appliance into any portion of mechanical draft system operating under positive pressure.

3.Vent connector should have the greatest possible initial rise above the draft hood consistent with the head room available and the required clearance from adjacent combustible building structure.

4.Install vent connector above bottom of chimney to prevent blockage - inspect chimney for obstructions or restrictions and remove - clean chimney if necessary.

5.Vent connector should slope upward from draft hood to chimney not less than one inch in four feet. No portion of vent connector should run downward or have dips or sags. Vent connector must be securely supported.

6.Use thimble where vent connector enters masonry chimney - keep vent connector flush with inside of flue liner.

7.Do not install Non-listed (AGA, CGA, CSA, ETL, or UL) vent damper or other obstruction in vent pipe.

8.Locate Boiler as close to Chimney as possible consistent with necessary clearances. See Section I: Pre-Installation.
