Leak Test Procedures

After connecting the gas supply, test for leaks. Use a 50/50 solution of liquid soap and water to test for 
leaks at gas fitting and joints. Apply water/soap solution with brush only - do not over apply. 

NEVER test 

with an open flame. 
WARNING: DO NOT USE AN OPEN FLAME TO TEST FOR LEAKS!
NOTE: Always perform a leak test any time the appliance has been moved or disconnected from the 
gas supply line.

The Damper Stop provided keeps your damper from 
accidentally closing during operation of your set.  

This 

Damper Stop must be installed onto your Damper at all 
times. NOTE: The damper clamp is designed to hold 
the damper plate open 3 inches.  However, the damper 
must be fully open when the log set is in operation.

Install the Damper Stop onto the edge of the damper plate.  
Attach by securing the bolt provided to the damper plate 
with an adjustable wrench. (Fig. 5)

If the Damper Stop does not fit, drill a 1/4” hole into the 
damper plate and install an 
anchor bolt with nut, at a 90 degree angle, so that the 
damper plate will remain fully open.

The proper finished installation of the Damper Stop is 
shown in Figure 6.  If the bolt fails to block the damper in 
an open position, the damper should be removed from the 
chimney.

To check your vent for proper drafting: 

Light a tightly 

rolled newspaper on one end and place it at the inside 
front edge of the fireplace.  Observe the smoke and be 
sure the vent is properly drawing it up the chimney.  If 
the smoke is drawn back into the room, extinguish the 
flame and remove any obstruction until proper venting 
is achieved.  If that fails, check with a qualified chimney 
sweep.
