Installation Safety Instructions - Field Controls 46334800 Manual

INSTALLATION SAFETY INSTRUCTIONS

CAUTION: The power venting system must be installed by a qualified installer. "Qualified Installer" means 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.
1. 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, CGA Standard B149.1-M91 or B149.2-M91, or refer to the General Installation Inspection section of this
manual.
2. Plan the vent system layout before installation to avoid the possibility of accidental contact with concealed wiring or
plumbing inside walls.
3. Single wall vent pipe (refer to Diagram B) may be used to join the appliance to the power venter. If proper clearances
cannot be maintained from combustible material, Type B vent pipe should be used. Refer to national or local codes for
guidelines.
4. Disconnect power supply before making wiring connections to prevent electrical shock and equipment damage.
5. 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.
6. Air flow adjustment MUST be made to ensure appliance efficiency. This should be done at the appliance exhaust
outlet with a velocity meter or draft gauge.
7. On gas-fired furnaces, a barometric draft control must be installed to regulate proper air flow and fluctuations in the
system's air flow during operation. Fluctuations may come from wind loads on the outlet of the power venter or house
depressurization during windy days.
8. The air pressure switch must be adjusted to assure safe operation. Failure to adjust the air pressure switch as
specified later in these instructions, could lead to improper operation of the venting system and furnace which will
result in product damage, personal injury, or death.
INSTALLATION OF SWG POWER VENTER
WARNING: Failure to install, maintain and/or operate the power venting system in accordance with the
manufacturer's instructions may result in fire, personal injury, or death.
P
ROCEDURE FOR CALCULATING TOTAL EQUIVALENT PIPE LENGTH IN FEET
1. Calculate the total equivalent feet for each type of fitting used in the venting system from Table 1 below.
2. Calculate the total amount of feet for the straight lengths of vent pipe.
3. Add the equivalent feet for the fittings with the total amount of feet of straight lengths. This will approximate the total
equivalent feet of the vent system. The total equivalent feet must be less than the maximum equivalent vent length as
shown in OEM instructions.
Table 1
EQUIVALENT LENGTH (FEET) OF VENT PIPE FOR VENT PIPE FITTINGS
VENT PIPE FITTINGS
90° ELBOW
45° ELBOW
Example: System Pipe Size = 4"
Step 1 Two 4" 90° Elbows @ 7 feet each = 14 Ft.
Step 2 Ten 2 Foot Lengths of 4" Pipe = 20 Ft.
Step 3 Total Equivalent Feet = 14 Ft. + 20 Ft. = 34 Ft.
