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 conrm 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  ame  still  on?  If  not,  the  reason  for  the  replace  shut  down  is  not  the  spill 
switch.
• Turn off the pilot ame and turn off all controls. Let replace to cool down. 
• Check for blockages or restrictions in the ue and venting components.
• Restart the replace and check for vent draft as described earlier.
• Operate the replace in a normal manner.
• If the main burner shuts down again after a period of operation, turn off the replace 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 ue connector is running from the drafthood into a non-combustible chimney 
the following optional nishing technique can be used.
CAUTION: Installations where the ue 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 replace, when tted with the Drafthood Adaptor, is a Natural Vent appliance 
and therefore draws air in through the Drafthood Adaptor intake ports.
