WARNING
All information in this manual is for
reference and guidance purposes,
and does not substitute for required
professional training, conduct,
and strict adherence to applicable
jurisdictional/professional codes and
regulations.
Do not use the boiler/burner as
support for ducted air piping.
Ducted piping must be supported
independently of the boiler.
Do not terminate venting into an
enclosed area.
Never use open fl ame or smoke from
a cigarette, cigar, or pipe as a testing
method during boiler installation,
operation, or maintenance.
Foreign substances, such as
combustible volatiles in the
combustion system can create
hazardous conditions. If foreign
substances can enter the air stream,
the boiler combustion air inlet must
be piped to an outside location.
Regular maintenance of the
fi lter is required (as per the fi lter
manufacturer’s recommendations) to
maintain the warranty.
Particulate matter or chemicals in
the combustion air supply to the
boiler will cause damage or failure to
the burner and is not covered under
warranty.
2. After assembly, wipe excess cement from pipe at end of fi tting socket.
A properly made joint will show a bead around its entire perimeter. Any
gaps may indicate a defective assembly due to insuffi
cient cement. Handle
joints carefully until completely set. Galvanized steel joints should be
sealed with adhesive aluminum tape.
Exhaust Venting
The Reliance boiler is equipped with a round vent connection (Figure 6) at the
lower rear of the boiler.
Standard Venting Confi guration, Category IV
The Reliance boiler is standardly confi gured as a Category IV appliance. The vent
connection sizes are adequate for a Category IV arrangement. Venting material
must be appropriate for condensing, positive pressure applications (condensing
occurs in the stack).
Adhere to the following:
1. Venting material supplied for the Reliance boiler confi gured as Category IV
must be AL29-4C or 316L SS, listed and labeled to UL 1738, and guaranteed
appropriate for the application by the manufacturer and supplier of the
venting.
2. Do not utilize automatic vent dampers or barometric dampers with the
Reliance boiler. Because the exhaust system operates at a positive pressure,
utilizing dampers could result in fl ue gases leaking into the boiler room.
3. The exhaust line must be sloped down toward a drain with a pitch of
at least ¼” per foot. Failure to do so can result in a condensate pocket,
which can result in an inoperative boiler. This must be no low spots in the
exhaust pipe, as this can also result in a condensate pocket. A high spot is
acceptable, provided the pitch from the high spot is maintained back to
the drain.
Optional Venting Confi guration, Category I
The Reliance boiler can be confi gured as a Category I appliance. The boiler must
be ordered this way from the factory. The operating controls will be confi gured
to limit the minimum modulation point to 50% of full input, thus preventing
condensing from occurring in the stack.
Adhere to the following:
1. Shipped loose with the boiler will be a stack increaser fi tting and a
barometric draft regulator. These components must be used when venting
the Reliance as a Category I appliance. The stack material must be 4”
diameter larger than the stack connection on the boiler.
2. Venting material must be appropriate for non-condensing, negative
pressure applications and should be B-Vent style material. This must be
guaranteed appropriate for the application by the manufacturer and
