VII. Venting

Install

vent system

in accordance with local building

codes; or local authority having jurisdiction; or

"Venting of Equipment", of the

National Fuel Gas

Code

, ANSI Z223.1/NFPA 54, or "Venting Systems and

Air Supply for Appliances", of the

National Gas and

Propane Installation Code

, CAN/CSA B149.1.

Install any of the following for this Independence Series

Category I, draft hood equipped appliance:
1. Type B or Type L gas vent. Install in accordance

with listing and manufacturer's instructions.

2. Masonry or metal chimney. Build and install in

accordance with local building codes; or local

authority having jurisdiction; or

Standard for

Chimneys, Fireplaces, Vents, and Solid Fuel

Burning Appliances

, ANSI/NFPA 211 and/or

National Building Code of Canada

Masonry chimney must be lined with approved clay

flue lining or listed chimney lining system

3. Single wall metal vent. Allowed by ANSI Z223.1/

NFPA 54 under very restrictive conditions.

4. Do not use cellular core PVC (ASTM F891),

cellular core CPVC, or Radel

(polyphenolsulfone).

5. Do not cover non-metallic vent pipe and fittings

with thermal insulation. Note: Non-metallic vent

cannot be used with this boiler.

Inspect chimney

and remove any obstructions or

restric tions. Clean chimney if previously used for solid

or liquid fuel-burning appliances or fireplaces.

DANGER

Inspect existing chimney before installing boiler.

Failure to clean or replace perforated pipe or tile

lining will cause severe injury or death.

Boiler Equipped With Vent Damper

1. Open Vent Damper Carton and remove Installation

Instructions. Read Installation Instructions thoroughly

before proceeding.

CAUTION

Do not use one vent damper to control two

heating appliances.
Provide adequate clearance for servicing -

6" (152 mm) minimum clearance between

damper and combustible construction.

NOTICE

DO NOT force the vent damper over the

rolled bead on the draft hood collar. The

vent damper should rest on the rolled bead.

Please refer to the specifications,

installation instructions and trouble

shooting guide packed in the vent damper

carton for complete detailed installation

instructions.

2. Vent damper should be same size as draft hood

outlet. See Figure 1. Unpack vent damper carefully

DO NOT FORCE CLOSED!

Forcing vent

damper may damage gear train and void warranty.

Vent damper assembly includes pre-wired

connection harness with polarized plug for use on

all 24V standing pilot or intermittent ignition (EI)

control systems.

3. Mount vent damper assembly on draft hood without

modification to either (Refer to instructions packed

with vent damper for specific instructions). Vent

damper position indicator to be visible to users

following installation.

4. USA - Do not install Non-listed vent damper or

other obstruction in vent pipe.

Canada - Do not install Non-listed vent damper or

other obstruction in vent pipe.

5. Arrange venting system so only the boiler is served

by vent damper supplied with boiler.

WARNING

This boiler needs fresh air for safe operation and must be installed so there are provisions for

adequate combustion and ventilation air.
Read, understand and follow combustion air instruction restrictions contained in the Pre-Installation

instructions of this manual.

Do not operate boiler where gasoline or other flammable vapors or liquids, or sources of hydrocarbons

(i.e. bleaches, cleaners, chemicals, sprays, paint removers, fabric softeners, etc.) are used, stored and/

or present in the air.
