The Tjerlund GPAK-
1 horizontal kit is certified for use
1.
Apply an adhesive bead around the
outside of the pipe approximately 1/4"
from the end of the pipe. This includes
the first fitting or pipe attached to the
furnace.
2.
Push the pipe and fitting together while
twisting the pipe or fitting. Twisting the
pipe or fitting spreads the adhesive
completely within the fitting socket.
3.
When the pipe is at the socket bottom,
inspect the joint. Look for a complete,
uninterrupted ring of adhesive material
around the pipe at the fitting socket.
Additional adhesive or rotation of the
pipe or fitting may be required for a
complete seal. The complete adhesive
material ring provides the seal required
for the positive pressure vent.
4.
All vent systems must include a tee and
drain plug for collection and disposal of
condensate. The drain tee must be
installed within the first 5 feet of vent run
to protect the furnace.
5.
All horizontal sections must have a
slope toward the drain tee of not less
than 1/4" per foot to prevent the collection
of condensate at any location other than
at the tee.
6.
Horizontal runs must be supported with
3/4" pipe strap at a maximum of 5 foot
intervals and at each point where an
elbow is used.
7.
Maintain a 6 inch minimum air space to
combustibles from all sections of the
stainless steel vent system, except
when a wall thimble is used.
with this furnace. The kit includes a power
venter, a side-wall vent hood and a barometric
draft control. It has an electrical interlock to
assure that the furnace will not operate when
the power venter is off.
The kit is for use only when exhaust is through
an exterior wall, normally with horizontal vent
piping. The power venter establishes negative
pressure in the vent piping and the furnace
operates as if connected to Category I vertical
venting.
Installation Instructions are provided with the
kit. Installation must conform to those instruc-
tions and applicable requirements of local codes.
! WARNING:
The entire vent system must be sealed
with a high temperature sealant which
will withstand temperatures of 450°F.
Recommended sealants: Dow Corning
Sealant 736 RTV; GE 106 RTV; High
Tech Ind., High TEMP RED.
