BOILER ROOM AIR SUPPLY AND VENTILATION

An ample supply of air is required for combustion and venti- lation. When buildings are insulated, caulked and weather- stripped, now or later on, direct openings to outside may be required and should be provided. If the boiler is not near an outside wall, air may be ducted to it from outside wall openings.

Provisions for combustion and ventilation air must be made in accordance with section 5.3, Air for Combustion and Venti- lation, of the National Fuel Gas Code, ANSI Z223.1-latest edition, or applicable provisions of the local building codes. The following recommendation applies to buildings of ener- gy-saving construction, fully caulked and weatherstripped.

INSTALLATION IN ENCLOSED BOILER ROOM REQUIRES TWO UNOBSTRUCTED OPENINGS FOR PASSAGE OF AIR INTO THE BOILER ROOM:

1.Air drawn horizontally from outdoors DIRECTLY through an outside wall; one louvered opening near the floor and one louvered opening near the ceiling, each opening with a minimum FREE air passage area of 1 square inch per 4000 Btuh of total appliances’ input.

2.Air drawn horizontally through HORIZONTAL DUCTS; one opening near the floor and one opening near the ceiling, each opening with a minimum FREE air passage area of 1 square inch per 2000 Btuh of total appliances’ input.

3.Air drawn VERTICALLY from outdoors; one opening at the floor and one opening at the ceiling, each opening with a minimum FREE air passage area of 1 square inch per 4000 Btuh of total appliances’ input.

4.Air drawn from inside the building; one opening near the floor and one opening near the ceiling, each opening with a minimum FREE air passage area of 1 square inch per 1000 Btuh of total appliances’ input.

IF BOILERS ARE INSTALLED ADJACENT TO OTHER FUEL BURNING EQUIPMENT, THE AREA OF FREE OPENINGS MUST BE APPROPRIATELY INCREASED TO ACCOMMODATE THE ADDITIONAL LOAD.

Openings must never be reduced or closed. If doors or win- dows are used for air supply, they must be locked open. Pro- tect against closure of openings by snow and debris. Inspect frequently.

No mechanical draft exhaust or supply fans are to be used in or near the boiler area.

The flow of combustion and ventilating air to the boiler must not be obstructed.

FLUE GAS VENTING REQUIREMENTS

The Victory II series boiler is a high efficiency, mechanically induced draft boiler and, therefore, requires different venting arrangements than natural draft, lower efficiency boilers.

THE FOLLOWING INSTRUCTIONS MUST BE CAREFULLY READ AND FOLLOWED IN ORDER TO AVOID ANY HAZ- ARDOUS CONDITIONS DUE TO IMPROPER INSTALLA- TION OF THE FLUE GAS VENTING SYSTEM.

The vent piping installation MUST be in accordance with these instructions and with ANSI Z223.1-latest edition NATIONAL FUEL GAS CODE, Part 7, Venting of Equipment. Other local codes may also apply and must be followed. Where there is a conflict between these requirements, the more stringent case shall apply.

The use of a vent damper is NOT permitted on this boiler series.

Approved Venting Applications

Victory II model VHS-90 through 180 are Category III and VHS-30 and 60 are Category II boilers, these boilers must be vented by proper 3" diameter venting system (see Cate- gory II and III venting - page 5).

Models VHS-90 through 180 are also Category I boilers when using a minimum of 5" diameter connector and vented into a natural draft chimney or Type “B” vent using a 3"x5" diameter vent adapter (see Category I venting - page 10).
