VERTICAL VENTING
Note:
The vent termination must be at least 3 feet (1
M) above the roof line and 2 feet (.61 m)
higher than any part of a structure within 10
feet (3.1 m). The total vertical distance of the
vent system from appliance flue collar to the
rain cap termination shall not exceed 20 feet.
The clearance to combustibles inside a chase
shall be no less than 4" (100 mm).
1.
Prior to beginning the installation, loosely
assemble all parts required to make sure all
parts are present.
2.
Locate position for venting system and
proceed to cut holes for firestop support and
firestop spacer. All vertical installations
require the use of a support.
3.
Refer to JOINT PROCEDURE (Figure 1)
before assembling system.
4.
Install system joining pipe as required up through
roof
(Figure 2 for WG24, WG30 & WG36;
Figure 2A for WG42, WG48, WG60; Figure 2B
for all WF models)
.
NOTE: A firestop must be provided when a vent
passes through a combustible floor or
ceiling. The opening must be framed as
for the support since the support also
serves as a firestop.
5.
The roof flashing can now be installed. Where
the vent passes through the roof a flashing must
be used to maintain the required clearances and
to protect from the elements. The framed
opening must be large enough to provide the
necessary clearances to combustibles, taking
into account the slope of the roof. The flashing
can be used on slopes from flat to 6/12 pitch.
Install the flashing while holding the pipe
centered in the opening. Fasten the flashing to
the roof under the roofing material upslope from
the pipe and above the roofing material below
the pipe. Seal as required using high
temperature silicone.
6.
Attach rain cap using the locking band as for
regular pipe joints.

FOR VENTING MODELS WG24, WG30 &
WG36 REFER TO FIGURE 3
.
For these models a vent box is required to be
installed on the front of the unit. The drain tee is
then supported by this box. The drain line is
also enclosed inside the box to protect it from
the weather.
To install this system first
TURN OFF ALL
POWER TO UNIT
. Install drain tee onto the
draft inducer transition after applying the high
temperature silicone sealant to ensure an
airtight seal between the tee and transition.
Using two (2) self-drilling screws (provided),
secure the tee with the drain stub in the straight
down or "six o'clock" position.
Knockout the 7/8" slug located in the front panel
just beneath the drain tee. Install one of the 7/8"
snap bushings in this hole. Route the silicone
drain tube through the unit as shown in Figure 5.
For WG24, WG30 and WG36 models, the drain
tube will then be run through the snap bushing
just below the drain tee and connected to the
drain tee stub.
Assemble vent box and install box seals as
shown in Figure 3A. Install vent box to the unit
as shown in Figure 3. There are a total of six
(6) holes that secure the vent box to the unit.
Three (3) of these holes are already punched
and three (3) will need to be drilled using an 1/8
inch drill bit.
FOR VENTING MODELS WF050, WF075,
WF100 & WF125 REFER TO FIGURE 4
.
The drain tee must be installed onto the draft
inducer transition. In order to do this the existing
3" stainless "straight through" connector must
first be removed.
TURN OFF ALL POWER TO
UNIT
. Unplug the inducer at the mating two pin
connector and remove inducer by removing five
(5) screws. Remove the "straight through"
connector and replace with the drain tee. The
drain tube must be in the down position. Use the
high temperature silicone sealant provided with
this kit to ensure an airtight seal between the
inducer outlet and the drain tee. Reinstall the two
screws in the drain tee and secure the inducer
and inducer gasket to the collector box with five
(5) screws. Plug in inducer.
