Installation
Venting Requirements and Options
The Wonderfire Direct Vent Heater must
be
located to allow
venting to the outside through a nearby wall. It may be
installed parallel to the wall and vented to the rear or it may
be installed
in
a corner and vented to either side. The
Wonderfire Direct Vent Gas Heater is approved only for
venting through a side wall with a horizontal termination.
The Wonderfire Direct Vent Gas Heater is approved for
venting with use of the following components available from
DuraVent Corporation or your Wonderfire dealer:

clearance
Common
vent
configuration
through
a
combustible
wall.
All Straight vent pipe sections have a net length 1-1/2' less
than the nominal dimension; i.e., a
6"
Straight pipe section has
an effective length of 4-1/2'.
The Appliance Adaptor 923V , when installed, terminates
12'(300 mm) above the stove.
Vent Clearances
When planning your installation, the location of the vent
terminal and clearances must be considered. Some of the
most common clearances to keep
in
mind are shown
on
these
pages.
IMPORTANT: ALL VENT CLEARANCES MUST
BE
MAINTAINED. CHECK YOUR VENT CLEARANCES
AGAINST APPENDIX
A,
PAGE
21.
The vent should
be
placed so that people cannot be
bumed
by
accidentally touching the vent surfaces when the
stove is operating,
The vent termination should
be
located where it cannot be
damaged
by
such things as automobile doors, lawnmowers or
snowblowers and it should be located away from areas where
it could become obstructed
by
snow, etc.
Some considerations are:
• Obstructions or impediments
to venting.
• Nearby combustible materials that could come into
contact with combustion exhaust gases.
• Other nearby openings (within
9")
through which exhaust
gas could re-enter the building.
• All vegetation within 3' that may interfere with the
draft
• Vinyl siding
requires
protection
from
vented
heat
directly
above
the
vent
opening.

The
location
of
the
vent
terminal
must
observe
minimum
clearances
to
these
common
outdoor
fixtures.
