Figure 5 - Installing and Removing 

the Glass Door

Installing the Glass Enclosure Panel

1. 

Retrieve the glass enclosure panel. Visually 

inspect  the  gasket  on  the  back  side  of  the 

frame. Gasket surface must be clean, free of 

irregularities and seated firmly.

2.

 Position the door in front of the firebox 

opening with the bottom of the door held 

away from the fireplace at a 45° angle (

Figure 

5

)

. Hook the top flange of the door frame 

over the top of the firebox frame.

3.

 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.

4.

 Reinstall the control compartment door 

(

Page 8

).

5.

 If the hood was uninstalled, reinstall the 

required 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 hood 

into the clips to secure.
