Initial Installation
4. After a minimum of 10 minutes operation, test the chimney draft with a smoke match at the top row
of the pattern to confirm that there is adequate draft or ‘pull’ at the openings around the body of the
Drafthood Adaptor, as shown in Figure 42.
AUTOMATIC SAFETY SHUT DOWN:
If the spill switch is activated and shuts off the main burner the following procedure should be
followed.
• Is the pilot flame still on? If not, the reason for the fireplace shut down is not the spill
switch.
• Turn off the pilot flame and turn off all controls. Let fireplace to cool down.
• Check for blockages or restrictions in the flue and venting components.
• Restart the fireplace and check for vent draft as described earlier.
• Operate the fireplace in a normal manner.
• If the main burner shuts down again after a period of operation, turn off the fireplace and contact your
service technician.
SPILL SWITCH REPLACEMENT:
Use the following instructions to replace the
Safety Spill Switch.
1. Turn the unit off and allow it to cool.
2. Disconnect the spill switch wires from the
valve and on/off/remote rocker switch wire
(see Figure 40).
3. Remove the four mounting screws holding the
spill switch bracket and remove the bracket
(see Figure 43).
4. Remove and replace the spill switch with a
50-885 Spill Switch Assembly using a T-20
torx type driver.
5. Follow the reverse of the previous steps.
OPTIONAL FINISHING:
In installations where the flue connector is running from the drafthood into a non-combustible chimney
the following optional finishing technique can be used.
CAUTION: Installations where the flue connector or venting connects to, or passes through,
combustible walls or ceilings, the inner vent components must be ‘B-vent’. It is not allowable
in these applications to use single wall inner vent components.
For decorative purposes a 6” (15 cm) single wall black stove pipe may be installed over the 4” (10 cm)
single wall or ‘B-Vent’.
Note: The use of these components is for aesthetic purposes only and does not effect the
fact that the fireplace, when fitted with the Drafthood Adaptor, is a Natural Vent appliance
and therefore draws air in through the Drafthood Adaptor intake ports.
