When using natural gas:
 Make sure the cap is installed in the propane/LP inlet of regulator.
 Use thread sealant to assure there are no leaks.
Propane/LP Gas
When using propane/LP gas:
 Make sure the cap is installed in the natural gas (NG) inlet of regulator.
 Use thread sealant to assure there are no leaks.
ADVERTENCIA: Asegúrese la tapa del regulador esté en la posición adecuada, 
como se muestra en los diagramas. La instalación y reparaciones deben ser realizadas 
por un técnico de servicio calificado solamente. 
Gas Natural

CAUTION: The heater requires an external regulator to reduce the LP tank pressure
to a maximum of 14" W.C. Never connect this product directly to the supply tank.
PRECAUCIÓN: El calentador requieres una externa regulador para reducir la presión
del tanque de gas a un máximo de 14" W.C. Nunca conecte este producto
directamente al tanque de suministro.
FOR NATURAL GAS SUPPLY
PARA LA FUENTE DE GAS DEL NATURAL
NOTICE: An additional gas regulator will be necessary if the local natural gas
pressure exceeds the heater's rated maximum inlet pressure. If in doubt, contact the
local gas utility. If natural gas inlet pressure exceeds 10" W.C., the safety pressure
switch will activate. See owners manual for proper procedure to bypass the
pressure switch.
AVISO: Un regulador de gas adicional será necesario si la presión del gas natural
local excede de entrada nominal máxima del calentador presión. En caso de duda,
póngase en contacto con la compañía de gas local. Si la presión de entrada de gas
natural supera los 10" WC, el interruptor de presión de seguridad se activará.
Consulte el manual del propietario para el procedimiento adecuado de derivación
el interruptor de presión.

This appliance may be installed in an aftermarket,* permanently 
located, manufactured (mobile) home, where not prohibited by 
local codes.
This appliance is only for use with propane or natural gas.
Field conversion by any other means including the use of a kit 
is not permitted.
WARNING: Make sure the supplied cap is installed in 
unused regulator fitting before connecting the 
correct gas supply line. 
WARNING: Do not use natural gas and propane gas 
together.
CAUTION: Two gas line installations at the same 
time are prohibited.
ADVERTENCIA: Asegúrese de que la línea no 
utilizado se conecta por primera vez antes de 
conectar la línea de suministro de gas correcta. 
ADVERTENCIA: No utilice el gas natural y el gas 
propano juntos.
PRECAUCIÓN: Dos instalaciones de líneas de gas al 
mismo tiempo están prohibidos.
INSTALLATION

Gas Line Access Into Stove Cabinet
* Purchase the optional CSA design-certied equipment 
shutoff valve from your dealer.
For  propane/LP  installations,  apply  pipe 
joint sealant lightly to male threads. This will 
prevent excess sealant from going into pipe. 
Excess sealant in pipe could result in clogged 
heater valves.
The installer must supply an external regula-
tor. The external regulator will reduce incom-
ing gas pressure. You must reduce incoming 
gas pressure to between 11" and 14" of w.c. 
If you do not reduce incoming gas pressure, 
heater regulator damage could occur. Install 
external regulator with the vent pointing down 
as shown in Figure 9. Pointing the vent down 
protects it from freezing rain or sleet.
Install sediment trap in supply line as shown 
in Figure 8. Place sediment trap where it is 
within reach for cleaning. Place sediment trap 
where trapped matter is not likely to freeze. 
A sediment trap traps moisture and contami-
nants. This keeps them from going into heater 
controls. If sediment trap is not installed or is 
installed wrong, heater may not run properly.
 WARNING: Test all gas piping 
and connections for leaks after 
installing or servicing. Correct 
all leaks at once (see page 14).
