If the pressure is not sufficient, ensure: 

1) the piping used is large enough. 

2) the supply regulator is adequately adjusted.

3) that  the total gas load for the residence does not exceed 
the amount supplied.

The supply regulator (the regulator that attaches directly to the 
residence inlet or to the propane tank) should supply gas at 
the suggested input pressure listed above.  Contact the local 
gas supplier if the regulator is at an improper pressure.

Pressure requirements for appliance are shown in the table 
below.

Proper input pressures required for optimum appliance per-
formance, gas line sizing requirements need to be followed 
from NFPA51.

NOTE:  A listed (and Commonwealth of Massachusetts 
approved) 1/2 inch (13mm) T-handle manual shut-off valve and 
flexible gas connector are connected to the 1/2 inch (13mm) 
control valve inlet. 
•  If substituting for these components, please consult local 

NOTE:  The gap between the supply piping and gas access 
hole may be  plugged with non-combustible insulation to prevent 
cold air infiltration.

NOTE:  Have the gas supply line installed in accordance with 
local building codes, if any.  If not, follow ANSI Z223.1.  Instal-
lation should be done by a qualified installer approved and/or 
licensed as required by the locality.  (In the Commonwealth of 
Massachusetts, installation must be performed by a licensed 
plumber or gas fitter.)

Leak test all gas line joints and the gas control valve prior 
to and after starting the fireplace.

Before making the gas connection, ensure that the appliance 
you are installing is designed for the type of gas being 
supplied.  This information can be found on the Ratings Label 
under the appliance.  If the appliance has been converted to 
propane (LP), the valve cover should have a label stating 
that the unit has been converted to propane.

Connect the gas line at the 3/8 in. (9.5mm) pipe connector 
on the valve at the back of appliance.   We recommend 
connecting the appliance with an approved flex gas line. 

 

If flex gas lines are not approved in your area, you must 
connect a hard pipe to the gas hookup.  

You must supply a manual shut-off valve in a visible location 
within 3 feet (914mm) of the appliance.

Fire Risk.
Explosion Hazard.
High pressure will damage valve.
•  Disconnect gas supply piping BEFORE 

pressure testing gas line at test pressures 
above 1/2 psig.

•  Close the manual shutoff valve BEFORE 

pressure testing gas line at test pressures 
equal to or less than 1/2 psig.

Verify inlet pressures.

•  Low pressure may cause explosion.
Install regulator upstream of valve if line pressure 
is greater than 1/2 psig.

Gas Leak Risk.
•  Support control when attaching pipe to 

prevent bending gas line.
