IMPORTANT:

This water heater must be installed strictly in accordance with the instructions enclosed, and local electrical, fuel and building codes. It is possible that connections to the water heater, or the water heater itself, may develop leaks. IT IS THEREFORE IMPERATIVE that the water heater be installed so that any leakage of the tank or relat- ed water piping is directed to an adequate drain in such a manner that it cannot damage the building, furniture, floor covering, adjacent areas, lower floors of the structure or other property subject to water damage. This is particular- ly important if the water heater is installed in a multi-story building, on finished flooring or carpeted surfaces. GSW WILL NOT ASSUME ANY LIABILITY for damage caused by water leaking from the water heater, pressure relief valve, or related fittings. Select a location as centralized within the piping system as possible. In any location selected, it is recommended that a suitable drain pan be installed under the water heater. This pan must limit the water level to a MAXIMUM depth of 45mm (1 3/4 in.) and have a diameter that is a minimum of 50mm (2 in.) greater than the diameter of the water heater. Suitable piping shall connect the drain pan to a properly operating floor drain. When used with a fuel-fired heater, this drain pan must not restrict combustion air flow.

In Earthquake Zones

Note: The water heater must be braced, anchored, or strapped to avoid moving during an earthquake. Contact local utilities for code requirements in your area.

Clearances and Accessibility

The minimum clearances between the heater and com- bustible materials are listed in Figure 1.

Note: These requirements are also listed on the data plate located on the front of the water heater.

A minimum of 600mm (24 in.) of front clearance and 100mm (4 in.) on each side should be provided for inspection and service.

an oil line break. Support the oil lines as required by applic- able codes. Make tank connections with swing joints or cop- per tubing to prevent breaking in case the tank settles. Make the swing joints so they will tighten as the tank settles. Non- hardening pipe joint compounds should be used on all threads. Do not use Teflon® tape as an oil pipe sealant as it can cause valves to fail and create hazards. Do not use compression fittings. Underground piping must be run in a casing to prevent oil from leaking into the ground or under the floor. Check local codes for more information.

Burner Installation

WARNING

This installation must be performed by a qualified Oil-Burner Technician in accor- dance with these instructions and diagrams. The installation and maintenance of the water heater must follow all of the instruc- tions in preceding sections of this manual. Improper installation can cause injury or property damage. Heater failure that is a result of the heating system is not covered by warranty.

The installation of these units shall be in accordance with the “Installation Code for Oil-Burning Equipment (CSA B139-04)”or “Standard for the Installation of Oil- Burning Equipment (NFPA 31)” (as applicable), local codes and the manufacturer’s instructions. The burner should be installed only by a qualified Oil-Burner Technician.

Oil Supply

All aspects of oil tank location and installation, tank size, oil piping supply and burners, including any fittings, valves, fil- ters or any fuel handling components must comply with:

•“Installation Code for Oil Burning Equipment (CAN/CSA-B139)”, (Canada).

•“Standard for the Installation of Oil-Burning Equipment. (NFPA 31)”, (U.S.A).

•Local codes and regulations.

•Information provided with burner and fuel pump.

Install the oil supply tank with fill and vent lines of adequate capacity as shown in Figure 4. When an appliance using a float valve between the supply tank and the burner is con- nected to a supply tank over 9 gallons (Can.) capacity, a valve operated by a fusible link shall be installed in the fuel line adjacent to, and upstream from, the float valve. If any part of fuel the oil tank is above level of the burner, an anti- siphon device must be used to prevent flow of oil in case of
