SPILL SWITCH
This is a thermally activated switch, attached to the back of the unit and extending up into the dilution draft hood, which senses the change in temperature and shuts down the gas valve in the event of a severe downdraft of air or a blocked or disconnected vent. It acts as a safety shutoff to prevent a build up of carbon monoxide or an explosion of unburnt gases during start up. If the flue is blocked or has no "draw", the spill switch will automatically shut off the supply of gas within about

VENTING ACTION CHECK
A check for correct venting action must be made before the installed insert is left with the customer.
Test after installing the unit into either the
1.Close all doors and windows in the room / start exhaust fans in the home / turn fireplace blower off.
2.Set controls to "high" and light the unit.
3.Wait 5 minutes. Light a match and hold it to the spill tube opening.
4.Venting action is satisfactory if smoke is drawn into the spill tube. Venting action is unsatisfactory if the flame and smoke are not drawn into the tube.
5.If venting action is unsatisfactory, turn the unit off, wait
10minutes and try again. If the smoke or flame is still not drawn into the spill tube, turn the unit off and check for adequate fresh air supply, vent blockage or restriction. If necessary, consult with a qualified inspector.

FINISHING
OPTIONAL BRICK PANEL INSTALLATION
Remove the se- curing screws lo- cated on either of the firebox sides as illustrated. Remove protective plastic wrap from all four panels. Centre the rear
brick panel against the back of the firebox. Place the left brick panel against the left side of the firebox, ensuring that it
butts up to the rear FIGURE 9a panel.
Excess material may be trimmed with a utility knife. Secure in place using a retainer bracket and 2 of the screws. Re- peat for the right side.
FIGURE9b
When shipped, the brick panels range in colour from white to varying shades of brown. During initial use, the panels will darken temporarily and emit a slight odour for a few hours. This is a normal condition that will not occur again. Simply open a window to sufficiently venti- late the room. The appearance of the panels will perma- nently lighten in colour with use.
