Fresh Air for Combustion and Ventilation

WARNING:

This heater must have fresh air for proper operation. If not, poor fuel combustion could result. Read the following instructions to insure proper fresh air for this and other fuel-burning appliances in your home.

Modern construction standards have resulted in homes that are highly energy-efficient and that allow little heat loss. Your home needs to breathe, however, and all fuel-burning appliances need fresh air to function properly and safely. Exhaust fans, clothes dryers, fireplaces and other fuel burning appliances all use the air inside the building. If the available fresh air supply is insufficient to meet the demands of these appliances, problems can result.

Provide for Adequate Ventilation

Any space within a home can be classified in these categories:

Unusually tight construction: The air that leaks around doors and windows may provide enough fresh air for combustion and ventilation. However, in buildings of unusually tight construction, you must provide additional fresh air. Unusually tight construction is defined as construction where:

Walls and ceilings exposed to the outside atmosphere have a continuous water vapor retarder with a rating of one perm or less with openings gasketed or sealed and;

Caulking or sealants are applied to areas such as joints around window and door frames, between sole plates and floors, between wall/ceiling joints, between wall panels, at penetrations for plumbing, electrical and gas lines, and at other openings.

Unconfined space: An unconfined space whose volume is not less than 50 cubic feet for each 1,000 Btu/Hr of the aggregate input rating of all appliances installed in that space. Rooms communicating directly with the space in which the appliances are installed, through openings not furnished with doors are consid- ered a part of the unconfined space.

Confined space: A confined space whose volume is less than 50 cubic feet for each 1,000 Btu/Hr of the aggregate input rating of all appliances in that space.

WARNING: You must provide additional ventilation air in a confined space.

For proper operation of the unit, provide fresh air opening(s) to the room. Follow the National Fuel Code NFPA54/ANSI Z223.1, for required size of combustion and ventilation openings.

NOTICE: A qualified service technician should install heater. Follow all local codes.

Gas Type

Verify the type of gas supply to be used, either natural gas or LP (Propane), and make sure the marking on the appliance rating plate agrees with that of the supply gas. The rating plate is located on the side of the heater, which indicates the type of gas the heater is orificed for.

Items Needed for Heater Installation

Before installing the heater, make sure you have these items:

•Gas piping (check local codes)

•Test gauge connection

•Sealant (resistant to LP gases) - approved thread compound

•Manual shut-off valve *

•Sediment trap - where required

•Ground joint union

•Tee joint and pipe wrench

*An installer supplied design-certified manual shut-off valve with 1/8” NPT tap connection.

Locating the Heater

This heater is designed to be mounted on a wall or on the floor.

WARNING: Never install the heater:

•in a bathroom *,

•in a recreational vehicle,

•where curtains, furniture, clothing or other flammable objects are less than 36” from the front, top, or sides of the heater,

•as a fireplace insert,

•in high traffic areas, or

•in windy or drafty areas.

*Models VCPV06M(N,P) permitted for bathroom installations.

WARNING: Vent-free heaters add moisture to the air. Although this is beneficial, installing heater in rooms without enough ventilation may cause mildew formation from too much moisture content. See National Fuel Code for Fresh Air for Combustion and Ventilation.
