AUTOMATIC VENT DAMPER

This heating boiler is design certified for use with the automatic vent damper (FIG. 15) part number printed on the boiler’s rating plate. A vent damper must be installed on all residential heating boilers with inputs of less than 300,000 Btu/hr to comply with minimum efficiency requirements. A vent damper is factory supplied with residential heating boilers with inputs of 45,000 thru 260,000 Btu/hr. A vent damper is optional on all heating boilers above 260,000 Btu/hr. A vent damper is available as an option on all water heaters.

The vent damper is a useful tool for saving energy when installed inside the living space where air can circulate freely around the appliance. The vent damper will not save as much, if any, energy if it is installed in locations such as:

-Unheated garage -Attic -Crawlspace

-Mechanical room that is vented outdoors

For installation and maintenance on the vent damper, refer to the instructions supplied with the vent damper.

Residential heating boilers with inputs of less than 300,000 Btu/hr must have the vent damper properly installed and the vent damper wire harness plugged into the terminal block on the side of the control panel to allow the boiler to function. Larger input heating boilers and water heaters will have a jumper plug installed in the terminal block to allow operation without a damper. Remove the jumper plug from the terminal block to connect an optional vent damper wire harness. The jumper plug MUST be in place if an optional vent damper is not used on water heaters and larger input heating boilers.

￿CAUTION

Do not install the vent damper within 6" (152 mm) of combustible materials.

Install the vent damper to service only the single appliance for which it is intended. If improperly installed, a hazardous condition such as an explosion or carbon monoxide poisoning could result.

The damper position indicator must be in a visible location with access for service following installation. The damper must be in an open position when appliance main burners are operating.

The part number for the automatic vent damper required on this heating boiler is printed on the rating plate. Vent damper regulations are design certified per the latest edition of ANSI Z21.66.

FIG. 15 Vent Damper and Vent Damper Terminal Block

￿WARNING

The vent damper must be installed directly on the flue outlet located on the top of the draft hood (see Figure 15). Do not alter the wire harness supplied with the vent damper. Follow the instructions supplied with the vent damper.

￿CAUTION

An appliance which is shut down or will not operate may experience freezing due to convective air flow down the flue pipe connected to the unit. Proper freeze protection must be provided, see Freeze Protection.
