Installation

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.

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 National Fuel Gas Code ANSI Z223.1/NFPA 54 and the National Electrical Code, NFPA 70. The former is available from the Canadian Standards Association, 8501 East Pleasant Valley Road, Cleveland, OH 44131, and both documents are available from the National Fire Protection Association, 1 Batterymarch Park, Quincy, MA 02269.

GROUNDING

The water heater when installed must be grounded in accordance with local codes, or in the absence of local codes:

In the United States

The National Electric Code, ANSI/NFPA 70.

HIGH ALTITUDE INSTALLATION

WARNING

STANDARD MODELS ARE FOR INSTALLATION UP TO 2,000 FEET (610m) ABOVE SEA LEVEL.

IF A STANDARD MODEL IS INSTALLED ABOVE 2,000 FEET (610m), INPUT RATING SHOULD BE REDUCED AT A RATE 4 PERCENT FOR EACH 1,000 FEET (305m) ABOVE SEA LEVEL WHICH REQUIRES REPLACEMENT OF THE BURNER ORIFICE IN ACCORDANCE WITH THE NATIONAL FUEL GAS CODE (ANSI Z223.1/NFPA 54).

FAILURE TO REPLACE THE STANDARD ORIFICE WITH A HIGH ALTITUDE ORIFICE WHEN INSTALLED ABOVE 2,000 FEET (610m) COULD RESULT IN IMPROPER AND INEFFICIENT OPERATION OF THE WATER HEATER, PRODUCING CARBON MONOXIDE GAS IN EXCESS OF SAFE LIMITS, WHICH COULD RESULT IN SERIOUS INJURY OR DEATH. CONTACT YOUR LOCAL GAS SUPPLIER FOR ANY SPECIFIC CHANGES WHICH MAY BE REQUIRED IN YOUR AREA.

LOCATION OF HEATER

The heater is design certified by the Canadian Standards Association for installation on combustible flooring in a closet having minimum clearances from combustible material of: 0" clearance from sides and rear, 5" from the front and 12" from the top. (Standard clearance.) If clearances stated on the heater differ from standard clearances, install water heater according to clearances stated on heater.

Adequate clearance for servicing this appliance should be considered before installation, such as changing the anodes, etc.

A minimum clearance of 5" must be allowed for access to replaceable parts such as the thermostats, drain valve and relief valve.

When installing the heater, consideration must be given to proper location. Location selected should be as close to the wall as practicable and as centralized with the water piping system as possible.

AIR REQUIREMENTS

Dilution air temperature must be 100°F or less. In calculating the free area of a vent opening, the blocking effect of screens, louvers and grills should be considered. Screens shall not be of a mesh smaller than 1/4 inch square. If the free area is not known, the current edition of National Fuel Gas Code ANSI Z223.1/NFPA 54 recommends using figures of 20-25 percent free area for wood louvers or 60-75 percent for metal grills or louvers.

UNCONFINED SPACE

In buildings of conventional frame, brick or stone construction, unconfined spaces may provide adequate air for combustion, ventilation, and dilution air for power venter.

If the unconfined space is within a building of tight construction (as defined in the most recent revision of the National Fuel Gas Code Handbook), air for combustion, ventilation, and venter dilution must be obtained from outdoors. The installation instructions for confined spaces must be followed.

Installation:	least 18” above the floor.
Do not install water heater	This will reduce, but not
where flammable products	eliminate, the risk of vapors
will be stored or used	being ignited by the main
unless the main burner and	burner or hot surface
hot surface igniter are at	igniter.

CONFINED SPACE

When drawing combustion and dilution air from inside a conventionally constructed building to a confined space, such a space shall be provided with two permanent openings; ONE WITHIN 12 INCHES OF THE ENCLOSURE TOP AND ONE WITHIN 12 INCHES OF THE ENCLOSURE BOTTOM. Each opening shall have a free area of one square inch per 1000 Btuh of the total input of all appliances in the enclosure, but not less than 100 square inches.

If the confined space is within a building of tight construction, air for combustion, ventilation and power venter dilution must be obtained from outdoors. When directly communicating with the outdoors or communicating through vertical ducts, two permanent openings, located in the above manner, shall be provided. Each opening shall have a free area of not less than one square inch per 4000 Btuh of the total input of all appliances in the enclosure. If horizontal ducts are used, each opening shall have a free area of not less than one square inch per 2000 Btuh of the total input of all appliances in the enclosure.

GPCR, GPSH specifications

A.O. Smith has long been a leader in the water heating industry, known for its innovation and commitment to quality. Among its standout products are the GPSH and GPCR series, which exemplify advanced technology and efficiency in water heating solutions.

The GPSH, or Gas Powered Storage Heater, is engineered to optimize energy usage while providing a continuous supply of hot water. This model features advanced thermostatic control, ensuring precise temperature management to meet user needs. Additionally, the GPSH boasts an impressive insulation system, reducing heat loss and resulting in improved energy efficiency.
