PREPARING FOR INSTALLATION
Before beginning assembly or operation of the product, make sure all parts are present. Compare parts with package
contents list and diagram above. If any part is missing or damaged, do not attempt to assemble, install or operate the
product. Contact customer service for replacement parts.
Before installing heater, make sure you have the items listed below:
• piping (check local codes)
• sealant (resistant to natural gas and propane/LP gas)
• equipment shutoff valve*
• test gauge connection*
• sediment trap
• tee joint
• pipe wrench
• flexible gas hose (check local codes)
* A CSA design-certified equipment shutoff valve with
1/8-inch NPT tap is an acceptable alternative to test
gauge connection. Purchase the optional CSA design-
certified equipment shutoff valve from your dealer.
WATER VAPOR: A BY-PRODUCT OF UNVENTED ROOM HEATERS
Water vapor is a by-product of gas combustion. An unvented room heater produces approximately one (1) ounce
(30 mL) of water for every 1,000 BTUs (.3 KWs) of gas input per hour. Unvented room heaters are recommended as
supplemental heat (a room) rather than a primary heat source (an entire house). In most supplemental heat applica-
tions, the water vapor does not create a problem. In most applications, the water vapor enhances the low humidity
atmosphere experienced during cold weather.
The following steps will help ensure that water vapor does not become a problem.
1. Be sure the heater is sized properly for the application, including ample combustion air and circulation air.
2. If high humidity is experienced, a dehumidifier may be used to help lower the water vapor content of the air.
3. Do not use an unvented room heater as the primary heat source.
