A. GENERAL

1. Install the

URE

IRE

boiler venting system in accordance

with these instructions and with the National Fuel Gas
Code, ANSI Z223.1/NFPA 54, CAN/CGA B149, and/or
applicable provisions of local building codes.

2. The

URE

IRE

boiler is a direct vent appliance and is

ETL Listed as a Category IV appliance with Intertek
Testing Laboratories, Inc.

3. Sources of combustion air contaminated with chlorine,

ammonia or alkali agents must be avoided. Do not
install this boiler near a swimming pool, hot tubs or
laundry. Do not store chemicals near the boiler.

B. APPROVED MATERIALS

1. Table 3.1 lists approved materials for vent pipe (and

adhesives where applicable). Use only these materials
for exhaust vent piping.

2. PVC pipe and fittings are not to be used for venting in

confined spaces such as closet installations. Use only
CPVC or polypropylene (InnoFlue or PolyPro) vent
pipe under these conditions.

3. Cellular core piping is approved for inlet air piping only.

* PVC pipe/fittings are not to be used for venting within

confined spaces.

Notice: Installations in Canada require compliance with
ULC S636 - Standard for Type BH Gas Venting Systems.

C. EXHAUST VENT/AIR INTAKE PIPE

LOCATION

1. Install vent piping before installing water, fuel, or

condensate piping. Working from largest to smallest
diameter reduces the complexity of piping
interferences.

2. Vent and air intake piping is to be installed so that

there is sufficient access for routine inspection as
required in Section 11, of this manual.

3. The vent piping for this boiler is approved for zero

clearance to combustible construction. However, a fire
stop must be used where the vent pipe penetrates
walls or ceilings.

4. The Peerless

URE

IRE

boiler, like all high efficiency,

gas-fired appliances, is likely to produce a vapor
plume due to condensation. Surfaces near the vent
termination will likely become coated with
condensation.

5. The maximum combined vent and air inlet vent length

for the Peerless

URE

IRE

boiler is about 200

equivalent feet (60 m).Be sure that the boiler is located
such that the maximum vent length is not exceeded.

VENTING & AIR INLET PIPING

3. VENTING & AIR INLET PIPING

of this venting system. Failure to comply may result
in serious injury, death or major property damage.

WARNING

Only the materials listed below are approved for use
with the

URE

IRE

boiler. Use only these components

in accordance with these instructions. Failure to use
the correct material may result in serious injury,
death, or major property damage.

WARNING

Table 3.1: Approved Materials for Exhaust Vent Pipe

Use of cellular core PVC (ASTM F891), cellular core
CPVC, or Radel

(polyphenolsulphone) for exhaust

vent is prohibited. Use of these materials as exhaust
vent may result in severe personal injury, death, or
major property damage.

WARNING
