VICTORY VSPH Models | 5 |
VENTING APPLICATION
VSPH Series are sealed combustion type boilers, they maybe installed and vented either as a direct vent boiler which all air for combustion is obtained directly from outside or as a non- direct vent boiler which air for combustion is taken from inside the boiler room.
VSPH boilers must be vented by proper 3" diameter stainless steel venting system (see “vent material” on this page) through the roof or sidewall.
BOILER ROOM AIR SUPPLY AND VENTILATION
An ample supply of air is required for combustion and ventila- tion. 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 Ventila- tion, of the National Fuel Gas Code, ANSI
INSTALLATION IN ENCLOSED BOILER ROOM REQUIRES TWO UNOBSTRUCTED OPENINGS FOR PASSAGE OF AIR INTO THE BOILER ROOM:
A.NON-DIRECT VENT INSTALLATION
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 open- ing 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 ceil- ing, 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 ACCOMMO- DATE THE ADDITIONAL LOAD.
B.DIRECT VENT INSTALLATION
Adequate air supply should be provided to prevent overheating of the boiler controls and boiler room. Openings for passage of air into the boiler room for
If additional
For both direct and
-Openings must never be reduced or closed. If doors or windows are used for air supply, they must be locked open.
-Protect 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.
-Boiler area must never be under negative pressure. The flow of combustion and ventilating air to the boiler must not be obstructed.
FLUE GAS VENTING REQUIREMENTS
The Victory VSPH series boiler is a high efficiency, mechanical- ly 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 INSTALLATION OF THE AIR INTAKE AND FLUE GAS VENTING SYSTEM.
The vent piping installation MUST be in accordance with these instructions and with ANSI
The use of a vent damper is NOT permitted on this boiler series.
