After the gas piping to the unit is complete, all connections
must be tested for gas leaks. This includes pipe connections
at the main gas valve, emergency shutoff valve and
other gas connectors. A soap and water solution can be
applied on each joint or union using a small paintbrush.
If any bubbling is observed, the connection is not sealed
adequately and must be retightened. Repeat the tightening
and soap check process until bubbling ceases.
• If pressure testing the gas supply lines at pressures
greater than 1/2 psig (14 inches WC), the unit must
be disconnected from the gas supply piping system
to prevent damage to the gas valve.
• If the test pressure is less than or equal to 1/2 psig
(14 inches WC), the unit must be isolated from the
gas supply line by closing the manual shut-off valve.
High Altitude Conversion
Conversion of this unit must be performed by qualified
service personnel, using only approved parts. All
installations must be made in accordance with the National
Fuel Gas Code and/or local jurisdiction codes.
High altitude conversion can be field performed by a simple
adjustment of manifold pressure or a change of the orifices
(if necessary) depending on type of gas being utilized. The
changes required depend on the installation altitude and
the heating value of the gas (based on sea level) which
can be obtained from your local gas utility. The heating
value of gas at high altitude is always lower than the sea
level heating value. The heating values listed in
Table 5
& Table 6, (page 16) are based on sea level values.
WARNING:
The reduction of input rating necessary for high
altitude installation may only be accomplished
with factory supplied orifices. Do not attempt to
drill out orifices in the field. Improperly drilled
orifices may cause fire, explosion, carbon
monoxide poisoning, personal injury or death.
If installing this unit above 2,000 feet, the input rate must
be reduced 4% per 1,000 feet of altitude (Example: 12%
at 3,000 feet, 16% at 4,000 feet, etc). NOTE: Deration is
necessary to compensate for low atmospheric pressure
at high altitudes.
For altitudes between 5,000 and 10,000 feet above sea
level, the unit can be converted by adjusting the furnace
manifold pressure. See
Table 5 for the correct manifold
pressure settings when using natural gas.
LP/Propane Gas Conversion
WARNING:
This unit was equipped at the factory for use
with natural gas only. A special kit, supplied by
the manufacturer, is required to convert the unit
to operate on LP/propane gas. Failure to use the
proper conversion kit can cause fire, explosion,
property damage, carbon monoxide poisoning,
personal injury, or death.
MPORTANT NOTE:
When converting this low NOx unit from natural gas
to propane (LP) gas, it is necessary to remove the
NOx baffles.
Conversion of this equipment to LP/Propane gas must
be made by qualified service personnel, using approved
factory parts. Conversion to LP can be accomplished by
replacing the natural gas orifices with the appropriate LP/
Propane orifices and then adjusting the manifold pressure
(
page 18 ). Conversion to LP/Propane (sea level and high
altitude) is detailed in the installation instructions provided
with the conversion kit.
Please follow the instructions
provided in each kit.
Approved conversion kits are:
• The United States LP/Propane Gas Sea Level and High
Altitude Conversion Kit is for LP/propane conversion in
the United States at altitudes between zero and 10,000
ft. above sea level.
• The Canadian LP/Propane Gas Sea Level and High
Altitude Conversion Kit is for LP/propane conversions
in Canada at altitudes between zero and 4,500 ft. above
sea level.
For installations between zero and 4,999 ft. above sea
level, a #55 drill size orifice should be used. Installations
5,000 ft. above sea level require a #56 drill size orifice.
Table 6, (page 16) lists the correct orifice size to use
at different altitudes.
After changing the orifices, it is required that you measure
the gas input rate by clocking the gas meter and using
the local gas heating value. See Verifying & Adjusting the
Firing Rate section on
page 18 .
AVERTISSEMENT:
RISQUE D’INDENDIE OU D’EXPLOSION
Le non-respect des avertissements de sécurité
pourrait d’entraîner des blessures graves, la
mort ou des dommages matériels.
Ne jamais utiliser une flamme nue por
vérifier la présence des fuites de gaz. Pour la
vérification de tous les joints, utiliser plutôt une
solution savonneuse commerciale fabriquée
spécifiquement pur la détection des fuites de
gaz. Un incendie ou une explosion peut entraîner
des dommages matériels, des blessures ou la
mort.
