GAS SUPPLY & PIPING
WARNING:
FIRE OR EXPLOSION HAZARD
• Failure to follow safety warnings exactly could
result in serious injury or property damage.
• Installation and service must be performed by
a qualified installer, service agency or the gas
supplier.
• Do not store or use gasoline or other flammable
vapors and liquids in the vicinity of this or any
other appliance.
WHAT TO DO IF YOU SMELL GAS
• Do not try to light any appliance.
• Do not touch any electrical switch; do not use
any phone in your building.
• Leave the building immediately.
• Immediately call your gas supplier from a
neighbor's phone. Follow the gas supplier's
instructions.
• If you cannot reach your gas supplier, call the fire
department.
AVERTISSEMENT:
RISQUE D'INCENDIE OU D' EXPLOSION
• Le non-respect des avertissements de sécurité
pourrait entraîner des blessures graves, la mort
ou des dommages matériels.
• L'installation et l'entretien doivent être effectués
par un installateur qualifié, un organisme de
service ou le fournisseur de gazstaller, service
agency or the gas supplier.
• Ne pas entreposer ni utiliser de l'essence ni
d'autres vapeurs ou liquides inflammables dans le
voisinage de cet appareil, ni de tout autre appareil.
QUE FAIRE S'IL Y A UNE ODEUR DE GAZ
• Ne pas tenter d'allumer aucun appareil.
• Ne toucher à aucun interrupteur électrique;
n'utiliser aucun téléphone dans le bâtiment.
• Évacuer l'immeuble immédiatement.
• Appeler immédiatement le fournisseur de gaz en
employant le téléphone d'un voisin. Respecter à
la lettre les instructions du fournisseur de gaz.
• Si personne ne répond, appeler le service des
incendies.
• All gas piping must be installed in compliance with
local codes and utility regulations. In the absence of
local codes the gas line installation must comply with
the latest edition of the National Fuel Gas Code ANSI
Z223.1 or CAN/CGA B149 Installation Codes.
• Some local codes require the installation of a manual
main shut-off valve and ground joint union external to the
unit. The shut-off valve should be readily accessible for
service and/or emergency use. Consult the local utility
or gas supplier for additional requirements regarding
placement of the manual main gas shut-off. See
7 (page
14).
• The manifold pressure must be set to the appropriate
value for your installation. Refer to the Manifold
Pressure Adjustment section
instructions.
• Gas piping must never run in or through air ducts,
chimneys, gas vents, or elevator shafts.
• Compounds used to seal joints on gas piping must be
resistant to the actions of LP propane gas.
• The main gas shutoff valve and main power disconnect
to the unit must be properly labeled by the installer in
case emergency shutdown is required.
• An 1/8 inch NPT plugged tap must be installed in
the gas line immediately upstream of the gas supply
connection to the unit for use when measuring the gas
supply pressure. The plug should be readily accessible
for service use.
• A drip leg should be installed in the vertical pipe run
to the unit. See Figure 7.
This unit only has right side gas entry. When connecting the
gas, provide clearance between the gas supply line and the
entry hole in the unit's casing to avoid unwanted noise and/
or damage to the unit. A typical gas service hookup is shown
in

sizes as a function of length in typical applications based on
nominal pressure drop in the line.
Leak Check
FIRE OR EXPLOSION HAZARD
Failure to follow safety warnings exactly could
result in serious injury or property damage.
Never test for gas leaks with an open flame. Use
a commercially available soap solution made
specifically for the detection of leaks to check all
connections. A fire or explosion may result causing
property damage, personal injury or loss of life.
AVERTISSEMENT:
RISQUE D'INDENDIE OU D'EXPLOSION
Si les consignes de sécurité ne sont pas suivies à la
lettre, cela peut entraîner la mort, de graves blessures
ou des dommages matériels.
Ne jamais vérifier la présence de fuites de gaz au
moyen d'une flamme nue. Vérifier tous les raccords
en utilisant une solution savonneuse commerciale
conçue spécialement pour la détection de fuites. Un
incendie ou une explosion risque de se produire,
ce qui peut entraîner la mort, des blessures ou des
dommages matériels.
After the gas piping to the unit is complete, all connections
must be tested for gas leaks. This includes pipe connections
Figure
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
