ANSI Z223.1/ NFPA 54 or National Standard of Canada, Natural Gas and Propane Installation Code, CSA B149.1. Installation of this furnace at altitudes above 2,000 ft. (610m) shall be made in accordance with the listed high Altitude Conversion Kit available with this furnace.

IMPORTANT:

Re-install the propane orifices to the same depth as the orifices supplied with the equipment.

See Table 15 for help in selecting orifices if orifice change is required. Furnace input rate and tempera- ture rise should be checked again after changing ori- fices to confirm the proper rate for the altitude.

Installations above 4,000 feet may require a pressure switch change. If required, use the BAYHALT*** Kit (High Altitude Accessory Kit) listed in PRODUCT DATA.

START UP AND ADJUSTMENT

PRELIMINARY INSPECTIONS

With gas and electrical power “OFF”

1.Duct connections are properly sealed

2.Filters are in place

3.Venting is properly assembled

4.Blower door is in place

Flip the switch on main gas valve within the unit to the “OFF” position. Turn the external gas valve to “ON”. Purge the air from the gas lines. After purging, Check all gas connections for leaks with a soapy solution — DO NOT CHECK WITH AN OPEN FLAME. Allow 5 min- utes for any gas that might have escaped to dissipate. LP Gas being heavier than air may require forced venti- lation. Flip the switch on the gas valve in the unit to the “ON” position.
