I) INTRODUCTION

We thank you for choosing a Flammable Vapor
Resistant Water Heater.

Your satisfaction with this product

is very important to us. This gas-fired water heater has been
developed to produce domestic hot water and may also be
used in combination with space heating applications. The
Flame Guard

TM

safety system is designed to reduce the risk

of flammable vapor related fires by trapping the burning
vapors within the water heater combustion chamber using
the special flame arrester. The burning vapors literally “burn
themselves out” without escaping back into the room.
