A. INTRODUCTION

WE RECOMMEND THAT THIS MANUAL BE REVIEWED THOROUGHLY BEFORE INSTALLING THE

WATER HEATER. SHOULD ANY QUESTIONS ARISE, NOT COVERED BY THIS DATA, CONTACT YOUR

LOCAL DISTRIBUTOR OR THE SERVICE DEPARTMENT AT THE FACTORY.

MODEL IDENTIFICATION

The model number of the water heater is found on the rating plate. Each model number identifies the application,

the construction and the function of the water heater , and provides a positive means of identification for application,

installation, operation, service and parts of the unit in a minimum amount of time.

RECEIVING EQUIPMENT

On receiving equipment it is suggested that you

• Review packing slip for the number of packages.

• Inspect for concealed damage immediately.

• Advise carrier, in writing, of shortages or damage.

• Claims are filed by the receiver against the carrier. The carrier, not the shipper, is responsible for any

shortage or damage whether visible or concealed.

B. INSTALLATION GUIDELINES

INSTALLATION REGULATIONS

THE INSTALLATION MUST CONFORM WITH THESE INSTRUCTIONS, REQUIREMENTS OR CODES OF

AUTHORITIES HAVING JURISDICTION, THE LATEST EDITION OF THE NATIONAL FUEL GAS CODE, ANSI

Z223.1 AND THE NATIONAL ELECTRICAL CODE.

ANY ALTERATION OR MODIFICATION TO THE WATER HEATER, ITS COMPONENTS OR ITS INTENDED

APPLICATION MAY VOID THE WARRANTY EXTENDED WITH THE PRODUCT BY THE MANUFACTURER.

WARNING: Improper installation, adjustment, alteration, service or maintenance can damage the

water heater, or create a hazard resulting in asphyxiation, explosion or fire.

WATER FLOW

Low water content heat exchangers require continuous flow for proper operation.

WATER CONDITIONS:

Domestic Hot water heaters are designed for operation with various water conditions. Corrosive water that has

high chlorine content or other chemicals require that the tubes in the heat exchanger be cupro-nickel. Provide us

with an analysis of water where this potential exists.

BASE REQUIREMENTS

Indoor water heaters must be installed on a level noncombustible surface, except as noted below. Do not install

on carpeting. Heater sizes 926 to 1758 Typhoon (Outdoor) are supplied with a combustible flooring base as

standard. The following chart lists the part number required for a combustible base, for water heaters supplied

without a combustible base.

COMBUSTION AND VENTILATION AIR SUPPLY

CAUTION: Combustion air must not be contaminated by corrosive chemical fumes which can damage the heater

and void the warranty.

IMPORTANT: Adequate air must be provided for proper combustion and ventilation of the surrounding area. An

inadequate supply of combustion air will result in incomplete combustion and eventual sooting of the heater.

Insufficient ventilation will cause excessive heat and rapid deterioration of electronic and electrical components.

Equipment rooms should be provided with TWO permanent air supply openings directly connected to outside air.

Each opening must have a minimum FREE area of one square inch per 4000 BTU per hour input of the total input

rating of all equipment in the room. Local codes or authorities having jurisdiction should be consulted for the following

table.
