When servicing water heater

•To avoid electric shock, disconnect electrical supply before performing maintenance.

•To avoid severe burns, allow water heater to cool before per- forming maintenance.

Operating restrictions

•Maximum domestic hot water temperature: residential sizes

— 160°F, commercial sizes — 180°F. Pay attention to the

water temperature warnings throughout this manual.

•Maximum boiler water temperature — 200°F.

•Maximum working pressure for tank — 150 PSIG.

•Water chemistry limits:

•hardness — less than 6 grains/gal.

•pH — above 6 and less than 8.

•chlorides — less than 200 ppm.

Boiler water restrictions

•Thoroughly flush the boiler system (without water heater connected) to remove sediment.

•The water heater heat exchanger can be damaged by build-up or corrosion due to sediment.

•Boiler water (including additives) must be practically non- toxic, having toxicity rating or class of 1, as listed in Clinical Toxicology of Commercial Products.

•If antifreeze is used in boiler system:

•Local codes may require a backflow preventer on cold water supply line.

•Use antifreeze specifically intended for hydronic heating systems. Inhibited propylene glycol is recommended.

•Follow boiler manual instructions for antifreeze usage.

•Do not use automotive, ethylene glycol or petroleum- based antifreeze. Do not use any undiluted antifreeze.

Location

•This water heater is not intended for outdoor installation.

•Install the water heater so if the tank or any connections should leak, the water flow will not cause damage to area near water heater, or to lower floors of structure. When such locations cannot be avoided, install a suitable drain pan under water heater. Drain pans are available at your local plumbing supply store.

•This product is designed for vertical installation only.
