INSTALLATION SAFETY INSTRUCTIONS
CAUTION: This device must be installed by a qualifi ed installer in accordance with the manufacturer's
installation instructions. Appliances should have a minimum of 75% combustion effi ciency
or have a maximum measured fl ue gas temperature of 550°F (Stainless steel units maximum
temperature rating 650°F US/575°F CA) at the inlet of the power venter.
1. The power venting system must be installed by a qualifi ed installer. "Qualifi ed Installer" shall mean an
individual who has been properly trained or a licensed installer. The installer must write or imprint his name,
phone number and date of installation on the installation tag. The tag should be attached to the power
venting system control kit box or power venter unit. Recording burner and venting system initial operational
information is strongly recommended as a guide for service or burner tune-up. Enter this in the space later in
this manual.
2. Safety inspection of a venting system should be performed before and after installing a power venting system
on an existing or new appliance. Procedures to follow are those recommended by the National Fuel Gas Code
ANSI Z223.1, or refer to the General Installation Inspection section of this manual.
3. Plan the vent system layout before installation to avoid the possibility of accidental contact with concealed
wiring or plumbing inside walls.
4. Single wall vent pipe (refer to Diagram B) may be used to join an appliance to the venting system, but if
proper clearances cannot be maintained from combustible materials, Class B Vent Pipe should be used for gas
appliances and Class L Type Vent Pipe for oil appliances. Refer to national or local codes for guidelines.
5. Disconnect power supply before making wiring connections to prevent electrical shock and
equipment damage.
6. This equipment is designed to overcome minor negative pressure conditions. To ensure extreme negative
pressure does not exist, follow the General Installation Inspection section of this manual.
7. Heating appliances equipped with draft hoods, such as boilers or furnaces, LP gas appliances, and Natural
gas appliances SHOULD have a secondary spillage switch installed. On appliances without draft hoods, it
is recommended that a secondary safety switch such as a WMO-1, GSK, FTS, or TSP-1 be used. Gas-fi red 30
millivolt power systems MUST be equipped with a spillage switch.
