Front  Glass  Enclosure  Panel,  Removal 

and Installation

Only doors certified with the appliance 

shall be used.

Seules  des  portes  certifiées  pour  cet 

appareil doivent être utilisées.

CAUTION: DO NOT abuse glass door by 

striking or slamming shut.

These  are  direct-vent  appliances.  They  are 

designed to operate only when the front glass 

enclosure panels are installed.  Generally the 

front glass enclosure panel should not be re-

moved except to gain access to the components 

within the firebox.  

Removing Glass Enclosure Panels

(see 

Figure 5)

1.

   To access the glass door securing latches, 

first open the lower control compartment 

door 

(

Figure 5

)

 by sliding and pulling the 

bottom panel forward.

2.

   Pull the latches forward and down to release 

them from the door channel.

3.

   Pull the bottom of the door out a few inches 

and grasp it on the right and left.  Gently lift 

to release the door from its channel above 

the door.  Pull the door forward.

4.

   Retrieve the glass door. Visually inspect the 

gasket on the backside of the frame. Gasket 

surface must be clean, free of irregularities 

and seated firmly. 

5.

   Inspect the gasket for defects.  Ensure it 

is properly located.  Make sure the bead is 

not rolled up into the channel at the top of 

the door, but remains flat against the top 

of the glass 

(see 

Figure 5

).

6.

   Position  the  door  in  front  of  the  firebox 

opening with the bottom of the door held 

away from the fireplace 

(

Figure 5

)

.  Hook 

the top flange of the door frame over the 

top of the firebox frame. 

7.

    Let  the  bottom  of  the  door  frame  swing 

gently in towards the fireplace ensuring that 

the gasket seats evenly as the door frame 

draws shut. Fasten the two latches located 

underneath the firebox floor to the door's 

vee-flange. Close both the latches securely.

8.

   If desired, install the optional hood.  Note 

the location of the three clips inside the top 

air channel above the door.  The clips are 

equally spaced on the top surface of the 

air channel opening.  Use a screwdriver to 

open the clips slightly if needed.  Engage 

the back edge of the eyebrow into the clips 

to secure.
