CONVERSIONS

HIGH ALTITUDE: In Canada, this furnace does not need to
be converted for high altitude (2000 - 4500 feet). It has been
certifi ed to operate at high altitude as manufactured.
In the United States, the modifi cations for high altitude are
based on a 4% reduction of input capacity for every 1000 feet
above 2000 feet above sea level. Table 6 illustrates the impact of
altitude for selected elevations. Consult with local fuel suppliers or
authorities to determine local regulations or customs.
NATURAL TO LP GAS: This series furnace is manufactured as a
natural gas appliance that may be converted to LP gas through
use of the Conversion Kit part number W370-0018. This kit
contains the conversion kit instructions, orifi ces needed for all
models, the regulator springs for the gas valve, and a label to
affi x adjacent to the appliance rating plate to alert subsequent service technicians of the conversion. The parts
removed for this conversion must remain with the furnace for any future conversion back to natural gas.

† Gas input ratings are certifi ed for elevations to 2000 ft. For elevations above
2000 ft, reduce ratings 2% for each 1000 ft above sea level.

13.1 CONVERSION STEPS

To convert from natural gas to LP gas, follow these steps:
1. Turn off gas supply to the furnace.
2. Shut off electrical power to the furnace.
3. Remove the front door to expose the gas train and
burner assembly.
4. Unfasten the ground joint union between the gas valve
and gas supply piping if applicable.
5. Unplug the wires connected to the gas valve.
6. Unfasten the burner manifold pipe from the burner
assembly. It is held in place by 2 screws on either end
of the manifold pipe.
7. Remove the existing orifi ces with a
open end wrench. Install the replacement orifi ces. The
orifi ce spuds are brass, and do not normally require
pipe dope. A light grease may be used to lubricate the
threads. The orifi ce spuds have tapered threads. DO
NOT OVER-TIGHTEN!!
8. Re-install the burner manifold pipe assembly following
steps 4, 5, and 6 in reverse order.
9. Remove the high fi re regulator cover screw from the
gas valve. See FIGURE 30.
