GAS SUPPLY
The serial plate indicates the type of gas the unit is equipped to burn. All Sierra equipment is adjusted at the factory.
Check type of gas on serial plate.
These models are design-certified for operation on natural or propane gases. For natural gas, the regulator is set to
deliver a 4" W.C. pressure to the manifold. For propane gas, it is set to deliver 10" W.C.
If applicable, the vent line from the gas appliance pressure regulator shall be installed to the outdoors in accordance with
local codes, or in the absence of local codes, with the National Fuel Gas Code, ANSI Z223.1, Natural Gas Installation
Code, CAN/CGA-B149.1, or the Propane Installation Code CAN/CGA- B149.2, as applicable.
This appliance should be connected ONLY to the type of gas for which it is quipped.
A 3/4" NPT line is provided at the rear for the gas connection. An adequate gas supply is imperative. Undersized or low
pressure lines will restrict the volume of gas required for satisfactory performance. Fluctuations of more than 25% on
natural gas or 10% on propane gas will create problems and affect burner operating characteristics.
An adequate gas supply line to the unit should be no smaller than the inside diameter of the pipe from the unit to which it is
connected.
Purge the supply line to clean out dust, dirt, or other foreign matter before connecting the line to the unit.
All pipe joints and connections must be tested thoroughly for gas leaks. Use only soapy water for testing on all gases.
NEVER use an open flame to check for gas leaks. All connections must be checked for leaks after the unit has been put
into operation. Test pressure should not exceed 1/4" W.C.
