This procedure must be done before
installing the appliance into the
masonry cavity.
The 739MN/MP and 739VN/VP
appliances are supplied with the
AutoFire vent collar slider plate
having an integral restrictor built-in.
When using the 720SWK-M Sidewall
Kit, the vent collar slider plate must
be replaced with one having no
restrictor (see instructions below).
The 739MN/MP and 739VN/VP do
not have restrictor plates behind the
rear log as other 739 models do.
1. Remove the existing vent slider
plate having built-in restrictor.
2. Replace with a vent slider plate
having no restrictor supplied
in this kit. (If more than 10’-0”
vertical vent run, vent plate
with
restrictor can remain in place).
