COMBUSTION AIR
Adequate combustion air is vital for proper combustion and for safe venting. Likewise, for proper SideShot performance, adequate
combustion air must be available to the appliance. Many installers assume adequate combustion air is present, especially in older
homes. In some cases this is a false assumption, because many older homes have been made "tight" due to weatherization. Size
the combustion air opening(s) into the appliance room as outlined NFPA 54/NFPA 211. When installing a SideShot, it is not nec-
essary to supply any more combustion air than normally required when conventional venting. Common symptoms of inadequate
combustion air include: Fan Proving Switch short cycling, odor present at the end of burner cycle, outside air enters the structure
through the SideShot Vent System on SideShot/Appliance off cycle.
SYSTEM OPERATION CHECK-OUT
1. Adjust thermostat or appliance controls to call for heat.
2. Verify that the SideShot operates first, prior to burner ignition.
Allow heating equipment and SideShot to operate continuously while performing steps 3-5.
3. Close all doors and windows of the building. If heating equipment is installed in utility room or closet, close the entrance door to
this room. Close fireplace dampers.
4. Turn on all appliances in the structure that exhaust indoor air during their operation, e.g. turn on clothes dryer, exhaust fans,
such as range hoods, bathroom exhaust and whole house fans.
5. Allow SideShot and equipment to operate for at least five minutes. Tripping of the burner circuit by the Fan Prover Switch dur-
ing the five minute operation indicates an unsafe operating condition. Turn fuel supply off to appliance and DO NOT OPERATE
UNTIL UNSAFE VENTING CONDITION IS INVESTIGATED BY QUALIFIED SERVICE PERSONNEL.
6. Turn thermostat or equipment controls to the "off" position. Verify that the post-purge timer operates the SideShot for several
minutes while burner is not firing before the SideShot turns off. Post-purge adjustment is made by turning the small slotted
screw. Counter clockwise will increase delay, clockwise will decrease delay. Overturning adjustment screw will damage timer.
7. Return all windows, doors and exhaust fans to their original conditions of use.

NOTES: All draft adjustments are approximate. This
chart is to be used for initial draft adjustment only.
Subsequent draft adjustments may be required to com-
pensate for various field conditions: wind, vent pipe
resistance, building pressure, multiple appliances, etc.
BTU/HR input ratings assume 30% or less excess air for
flame retention burners and 50% to 100% excess air for
conventional oil burners.
Do not exceed the recommended BTU/HR input range
of the SideShot.
Under no circumstances shall the minimum draft adjust-
ment be used for the larger input range of this product.
Improper draft adjustment may result in the dispersion
of flue products/carbon monoxide into the building inte-
rior.
