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 at the inlet of the 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 venter
unit. Recording burner and venting system initial operational information is recommended as a guide for
service or burner tune-up. Enter this in the space provided 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 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. 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 and natural gas appliances
SHOULD have a secondary spillage switch installed. On appliances without draft hoods, it is recommended
that the secondary safety switch GSK-3 be installed into the system. Gas-fi red 30 millivolt power systems
MUST be equipped with a spillage switch.
