WARNING:
All gas piping must conform with local building
codes, or in the absence of local codes, with the
most recent edition of CGA B149.1. DO NOT attempt
to modify, or tap into existing gas lines yourself. Fire
or explosion may result causing property damage,
personal injury or loss of life. Failure to follow the
safety warnings exactly could result in serious injury,
death or property damage.
WARNING:
All electrical wiring must comply with the latest
edition of the Canadian Electrical Code (CsA
C22.1 and/or local codes). Failure to follow these
instructions could result in possible damage to
equipment, serious personal injury, or death.

5. Remove the White wire from the LOW (M) terminal, the Brown
wire from the HI terminal, and the Black wire from the Common
(C) terminal of the gas valve.
6. Using two wrenches remove supply gas line, gas valve, and
factory gas piping back to the manifold elbow. DO NOT ALLOW
The BuRNeR ASSemBLY TO ROTATe.
7. Remove the four (4) fasteners that secure the gas manifold
to the burner box, as shown in Figure 1. Carefully remove the
gas manifold assembly from the burner box. NOTE: The gas
manifold consists of the gas manifold and the orifices.
8. Carefully remove the burner orifices from the gas manifold,
as shown in Figure 1.
9. Remove the four fasteners that secure the burner box to the
heat exchanger mounting panel, as shown in Figure 1.
10. Carefully remove the burners from the mounting bracket
and set screws aside for later use. Note the alignment of
the burners for reassembly purposes.
NOTE: Care should be taken to ensure no damage occurs to
the spark ignitor, flame sensor, or roll out limit switch.
CONVERTING TO LP / PROPANE GAs
(AT ALTITuDeS BeTWeeN ZeRO & 7,000 FT.)
1. Examine the rating plate of the unit to determine Model number
and rated input (Btu/hr).
2. Count the number of burners in the burner box. Verify all
information in Table 2 (page 6) to determine the appropriate
LP gas orifice size for your application.
3. Install the appropriate LP gas burner orifices into the gas
manifold.
NOTE: The size of the new orifices that will be installed into
the unit will depend upon the type of conversion (sea level
or high altitude). Please refer to the high altitude deration
section and Table 2 (page 6) for more details on your particular
conversion.
WARNING:
Do not use Teflon tape or pipe joint compound
on the orifice threads. The hole in the orifice may
become blocked and cause fire, explosion, property
damage, carbon monoxide poisoning, personal
injury, or death.
