To open the outside air shutter, open the bottom 
control access panel, and pull the outside air 
control lever all the way out. The outside air 
shutter should be fully open when the fi replace 
is in use and completely closed when the fi re-
place is not being used.  Closing it when not in 
use will prevent outside cold air from entering 
the dwelling.

The hand operated outside air control lever is 
located on the right side  of the fi replace open-
ing. 

See Figure 5.

To open the outside air , open the bottom control 
access panel, reach into the gap between the 
fi rebox bottom  and pull the outside air control 
lever all the way out.

The outside air shutter should be fully open when 
the fi replace is in use and completely closed 
when the fi replace is not being used.  Closing 
it when not in use will prevent outside cold air 
from entering the dwelling.

Operate the actuator through several cycles 
including the closed position.  Ensuring proper 
operation and freedom of movement.  Return 
the actuator arm to the closed position.

       WARNING 

Do not operate the shutoff lever 
unless a complete outside  com-
bustion air system has been 
installed with your appliance.

Outside Combustion Air Controls

Many appliances are equipped, when installed, 
with an outside (make-up air) vent system 
that is designed to provide the appliance with 
outside make-up air for combustion when in 
operation. 

 The outside air control lever for the outside 
air system is standard on all appliances but 
should not be operated if the complete system 
is not installed. Refer to 

Figure 5

.  When the 

complete outside air vent system is installed, 
the installer will remove the securing screw 
from the combustion air control lever located 
on the right side of the fi replace opening. 

If the securing screw has not been removed 
and you have reason to believe that you have 
a complete outside air system, contact your 
distributor to have your appliance inspected for 
the presence of the complete system.  DO NOT 
assume that you have this system in place.

Inspect Venting System

The appliance and venting system should be 
thoroughly inspected before initial use and at 
least annually by a qualifi ed service technician 
(inspection should include ensuring that exhaust 
or intake passages are unobstructed and vent 
components are properly assembled and not dam-
aged). If the venting system is disassembled for 
any reason, a qualifi ed service technician should 
follow vent installation instructions for proper 
reassembly and proper sealing of the venting 
system components. However, more frequent 
periodic inspections and cleanings should be 
performed by the homeowner. 

Clean Lower Control Compartment

Keep lower control compartment clean by vacu-
uming or brushing it out at least twice a year (also 
clean the air venturi with a brush or wire).  More 
frequent cleaning may be required due to accumula-
tion of lint from carpeting, bedding materials, pet 
hair, spider webs, etc.  

It is very important that 

control compartments, burners, circulating air 
passageways and air venturi on the appliance 
are NOT obstructed in any way.

MAINTENANCE

Cleaning Glass

(see

 Front Glass Enclosure Panel, Removal and 

Installation

 on 

Page 9

 ) Note:  Clean glass after 

fi rst two weeks of operation (after Burn-In period 
is over) and then only when necessary and when 
the fi replace is cool.  Wipe surface with clean, 
dampened, soft cloth. Follow with dry, soft 
towel as desired. Take care not to scratch the 
glass surface.

The viewing glass should be cleaned periodically 
to remove any build-up caused from the fol-
lowing:

(See Maintenance Schedule, 

Page 20 

)

Refer to the maintenance schedule for maintenance 
tasks, procedures, periodicity and by whom they 
should be performed.  Always verify proper opera-
tion of the appliance after servicing.

•  During start-up, it is normal for condensation to 
form on the inside of the glass (this condensation 
and fog will usually disappear in a few minutes). 
The moisture can cause lint, dust and other air-
borne particles to cling to the glass surface. 
• Initial curing of the high temperature paint and 
burning off of lubricants used in the manufacturing 
process may result in a fi lm on the glass.  
• A white coating may form on the glass as a result 
of impurities and minerals in the fuel.

It is recommended that the glass be cleaned 
two or three times during each heating season, 
depending on the circumstances present.

The following cleaning solutions are approved for 
use to clean glass:

• Non-ammonia based household cleaner
• 50%-50% mix of white vinegar & water
• gas fi replace/stove glass cleaner 

Inspect Glass Gasket 

-   Visually inspect the 

gasket on the backside of the glass enclosure 
panels. The gasket surface must be clean, free 
of irregularities and seated fi rmly.

     WARNING

Turn off gas and electrical power 
before servicing the appliance

.

     

CAUTION

Wear gloves and safety  Glasses 
for protection while doing 
required maintenance

.

       IMPORTANT

Always verify proper operation 
after servicing.

       

IMPORTANT

Do not use abrasive cleaners on 
glass. Never clean glass when hot.

Before re-lighting the fi replace, refer to the 
lighting instructions in this manual. Instruc-
tions are also found on pull-out panels 
located below the glass door in the control 
compartment.
