INSTALLING THE NEW WATER HEATER

REQUIRED ABILITY

INSTALLATION OR SERVICE OF THIS WATER HEATER REQUIRES ABILITY EQUIVALENT TO THAT OF A LICENSED TRADESMAN IN THE FIELD INVOLVED. PLUMBING, AIR SUPPLY, VENTING AND GAS SUPPLY ARE REQUIRED.

INSPECT SHIPMENT

There may be hidden damage caused in transit. Check to be certain all parts of the venting system, as listed below, are present. CAUTION!!! IF THERE ARE ANY DAMAGED

PARTS, DO NOT INSTALL THIS WATER HEATER. REPORT ANY SHORTAGE TO YOUR DISTRIBUTOR OR DAMAGE TO YOUR CARRIER.

GENERAL

The installation must conform to these instructions and the local code authority having jurisdiction. In the absence of local codes, the installation must comply with the current editions of the “Nat- ural Gas and Propane Installation Code” CAN/CSA-B149.1. The code is available from the Canadian Standards Association, 5060 Spectrum Way, Mississauga, Ontario, Canada, L4W 5N6.

WATER PIPING

HOTTER WATER CAN SCALD:

Water heaters are intended to produce hot water. Water heated to a temperature which will satisfy space heating, clothes wash- ing, dish washing, cleaning and other sanitizing needs can scald and permanently injure you upon contact. Some people are more likely to be permanently injured by hot water than others. These include the elderly, children, the infirm, or physically/men- tally handicapped. If anyone using hot water in your home fits into one of these groups or if there is a local code or state law requiring a certain temperature water at the hot water tap, then you must take special precautions. In addition to using the low- est possible temperature setting that satisfies your hot water needs, a means such as a *mixing valve, should be used at the hot water taps used by these people or at the water heater, see Figure 2. Valves for reducing point of use temperature by mixing cold and hot water are also available:

Consult a Qualified Installer or Service Agency. Follow man- ufacturer’s instructions for installation of the valves. Before changing the factory setting on the thermostat, read the “Tem- perature Regulation” section in this manual.

This water heater shall not be connected to any heating systems or component(s) used with a non-potable water heating appli- ance.

All piping components connected to this unit for space heating applications shall be suitable for use with potable water.

Toxic chemicals, such as those used for boiler treatment shall not be introduced into this system.

When the system requires water for space heating at tem- peratures higher than required for domestic water purposes, a *mixing valve must be installed. Please refer to Figure 2 for suggested piping arrangement.

Water supply systems may, because of such events as high line pressure, frequent cut-offs, the effects of water hammer among others, have installed devices such as pressure reducing valves, check valves, back flow preventers, etc. to control these types of problems. When these devices are not equipped with an internal by-pass, and no other measures are taken, the devices cause the water system to be closed. As water is heated, it expands (thermal expansion) and closed systems do not allow for the expansion of heated water.

The water within the water heater tank expands as it is heated and increases the pressure of the water system. If the relieving point of the water heater’s temperature-pressure relief valve is reached, the valve will relieve the excess pressure. The temperature-pressure relief valve is not intended for the constant relief of thermal expansion. This is an unacceptable condition and must be corrected.

It is recommended that any devices installed which could create a closed system have a by-pass and/or the system have an ex- pansion tank to relieve the pressure built by thermal expansion in the water system. Expansion tanks are available for ordering through a local plumbing contractor. Contact the local water supplier and/or a service agency for assistance in controlling these situations.

NOTE: To protect against untimely corrosion of hot and cold water fittings, it is strongly recommended that di-electric unions or couplings be installed on this water heater when connected to copper pipe.

All gas piping must comply with local codes and ordinances or with the “Natural Gas and Propane Installation Code” CAN/ CSA-B149.1 whichever applies. Copper and brass tubing and fittings (except tin lined copper tubing) shall not be used.
