GB300 BOILER INSTALLATION AND OPERATION INSTRUCTIONS

BOILER RATINGS & CAPACITIES

Before undertaking the installation of the GB300(S,W) boiler check the boiler rating plate to ensure that the boiler has been sized properly for the job. The rating label has been packed with the controls. The “Net I=B=R Ratings” specify the equivalent amount of direct cast iron radiation that the boiler can supply under normal conditions. Also ensure that the boiler has been set up for the type of gas available at the installation site. Other important considerations are the availability of an adequate electrical supply, fresh air for combustion and a suitable chimney or vent system.

BOILER LOCATION

1.Locate the boiler in an area that provides good access to the unit. Servicing may require the removal of jacket panels. Allow a minimum clearance of 2 ft, 0.61 m between adjacent construction and the boiler sides and draft hood. A minimum clearance of 4 ft, 1.22 m must be maintained between the front of the boiler and adjacent construction. Accessibility clearances should take precedence over fire protection clearances, or use which ever is greater.

2.An optimum site will be level, central to the piping system, close to a chimney and have adequate fresh air for combustion.

3.Ensure that the floor is structurally sound and will support the weight of the boiler. Never install a GB300(S,W) on a concrete floor that contains wires, cables, water pipes or hoses. This boiler is designed for non combustible floors only! Never install this boiler on combustible materials or carpeting even if a noncombustible foundation material is placed over them!

WARNING: Never install a GB300(S,W) boiler on top of combustible flooring! Failure to comply with this warning may result in a fire causing extensive property damage, severe personal injury or death!

4. DO NOT install this boiler in a location that would subject any of the gas ignition components to direct contact with water or excessive moisture during operation or servicing. A full concrete foundation is recommended to protect the boiler from moisture and debris, Figure 1.

NOTE: The boiler must be assembled on a level, noncombustible surface. If the floor is not level a pad must be poured to provide a level surface. If a concrete block base is used level it using noncombustible shims or grout.

5. DO NOT place this boiler in a location that would restrict the introduction of combustion air into the boiler.

WARNING: Never store combustible materials, gasoline or any product containing flammable vapors or liquids in the vicinity of the boiler. Failure to comply with this warning can result in an explosion or fire causing extensive property damage, severe personal injury or death!

GB300 BOILER INSTALLATION AND OPERATION INSTRUCTIONS

COMBUSTION AIR & VENTILATION

WARNING: This boiler must be supplied with combustion air in accordance with Section 5.3, Air for Combustion & Ventilation, of the latest revision of the National Fuel Gas Code, ANSI Z223.1/NFPA 54 and all applicable local building codes. Canadian installations must comply with CAN/CGA B149.1 or .2 Installation Code. Failure to provide adequate combustion air for this boiler can result in excessive levels of carbon monoxide which can result in severe personal injury or death!

WARNING: Never operate a GB300 in an environment subjected to a negative pressure unless it is Direct Vented. Failure to comply with this warning can result in excessive levels of carbon monoxide causing severe personal injury or death!

To operate properly and safely this boiler requires a continuous supply of air for combustion. Oxygen is used by the boiler burners to burn the gas. NEVER store objects on or around the boiler. In addition, air is also used to assist in the safe disposal of the products of combustion. This air is known as dilution air and mixes with the products of combustion to assist in their exit through the flue pipe and chimney. An adequate supply of air must be available to replace the air used by these processes.

Older buildings often have enough natural infiltration to provide an adequate amount of combustion air provided that the demand for combustion air is not too great.

Buildings that are relatively new or “tight” will most likely require the installation of a fresh air duct or other means of providing make-up air. Any building utilizing other gas burning appliances, a fireplace, wood stove or any type of exhaust fan must be checked for adequate combustion air when all of these devices are in operation at one time. Sizing of an outside air duct must be done to meet the requirements of all such devices.

All Air From Inside The Building

If the boiler is to be located in a confined space minimum clearances of 2 ft, 0.61 m must be maintained between the boiler and any adjacent construction. When installed in a confined space two permanent openings communicating with an additional room(s) are required. The combined volume of these spaces must have sufficient volume to meet the criteria for an unconfined space. The total air requirements of all gas utilization equipment, fireplaces, wood stoves or any type of exhaust fan must be considered when making this determination.

Each opening must have a minimum free area of 1 in2/1000 Btu/hr, 2200 mm2/kW based on the total input rating of ALL gas utilization equipment in the confined area. Each opening must be no less than 100 in2, 64,516 mm2 in size. The upper opening must be within 12 in, 300 mm of, but not less than 3 in, 80 mm from, the top of the enclosure. The bottom opening must be within 12 in, 300 mm of, but not less than 3 in, 80 mm from, the bottom of the enclosure.

All Air From Outside The Building

When installed in a confined space two permanent openings communicating directly with, or by ducts to, the outdoors or spaces that freely communicate with the outdoors must be present. The upper opening must be within 12 in, 300 mm of, but not less than 3 in, 80 mm from, the top of the enclosure. The bottom opening must be within 12 in, 300 mm of, but not less than 3 in, 80 mm from, the bottom of the enclosure.

Where directly communicating with the outdoors or communicating with the outdoors through vertical ducts, each opening shall have a minimum free area of 1 in2/4000 Btu/hr, 550 mm2/kW of the total input rating of all of the equipment in the enclosure.

Where communicating with the outdoors through horizontal ducts, each opening shall have a minimum free area of 1 in2/2000 Btu/hr, 1100 mm2/kW of the total input rating of all of the equipment in the enclosure.

When ducts are used, they must have the same crosssectional area as the free area of the opening to which they connect.

When calculating the free area necessary to meet the make-up air requirements of the enclosure, consideration must be given to the blockage effects of louvers, grills and screens. Screens must have a minimum mesh size of 1/4 in, 6.4 mm. If the free area through a louver or grill is not known ducts should be sized per Table 1 below.

NOTE: These sizes are based on a 20 foot chimney height.

When more than one appliance is connected to the same chimney flue the flue must be large enough to safely vent the combined output of all the appliances.

WARNING: If an appliance using any type of a mechanical draft system operating under positive pressure is connected to a chimney flue, never connect any other appliances to this flue. Doing so can result in the accumulation of carbon monoxide which can cause severe personal injury or death!

VENT CONNECTIONS

Always use a type B or single wall galvanized metal vent pipe the same diameter as the draft hood flue collar. Use the shortest, straightest vent system possible for the installation. If horizontal runs exceed 6 feet they must be supported at maximum 6 foot intervals with overhead hangers. The vent system should be sloped up towards the chimney at a minimum rate of 1/4 inch/foot and terminate flush with the inside of the chimney flue. Fasten each connection with at least 3 corrosion resistant sheet metal screws.

WARNING: Never modify or alter any part of the boiler’s draft hood. This includes the removal or alteration of any baffles. Never install a vent pipe of a diameter different than that of the boiler draft hood flue collar. Failure to comply with this warning can result in severe personal injury or death.

Always provide a minimum clearance of 6 inches between type C vent pipe and any combustible materials. Type B1 vent may be used, clearance between it and any combustible material must be as listed.

WARNING: Failure to maintain minimum clearances between vent connectors and any combustible material can result in a fire causing extensive property damage, severe personal injury or death!

GB300 BOILER INSTALLATION AND OPERATION INSTRUCTIONS

COMMON VENT SYSTEMS

If an existing boiler is removed from a common venting system, the common venting system may then be too large for the proper venting of the remaining appliances connected to it. At the time of removal of an existing boiler, the following steps shall be followed with each appliance remaining connected to the common venting system placed in operation, while the other appliances remaining connected to the common venting system are not in operation.

Au moment du retrait d'une chaudière existante, les mesures suivantes doivent être prises pour chaque appareil toujours raccordé au système d'évacuation commun et qui fonctionne alors que d'autres appareils toujours raccordés au système d'évacuation ne fonctionnent pas: système d'évacuation.

a.Seal any unused openings in the common venting system.

Sceller toutes les ouvertures non utilisées du système d'évacuation.

b.Visually inspect the venting system for proper size and horizontal pitch and determine there is no blockage or restriction, leakage, corrosion and other deficiencies which could cause an unsafe condition.

Inspecter de façon visuelle le système d'évacu-ation pour déterminer la grosser et l'inclinaison horizontale qui conviennent et s'assurer que le système est exempt d'obstruction, d'étranglement de fruite, de corrosion et autres défaillances qui pourraient présenter des risques.

c.Where it is practical, close all building doors and windows and all doors between the space in which the appliances remaining connected to the common venting system are located and other spaces of the building. Turn on clothes dryers and any appliance not connected to the common venting system.

Turn on any exhaust fans, such as range hoods and bathroom exhaust, so they will operate at maximum speed. Do not operate a summer exhaust fan. Close fireplace dampers.

Dans la mesure du possible, fermer toutes les portes et les fenêtres du bâtiment et toutes les portes entre l'espace où les appareils toujours raccordés du système d'évacuation sont installés et les autres espaces du bâtiment. Mettre en marche les sécheuses, tous les appareils non raccordés au système d'évacuation commun et tous les ventilateurs d'extraction comme les hottes de cuisinère et les ventilateurs des salles de bain. S'assurer que ces ventilateurs fonctionnent à la vitesse maximale. Ne pas faire fonctionner les ventilateurs d'été. Fermer les registres des cheminées.

d.Place in operation the appliance being inspected. Follow the lighting instructions. Adjust thermostat so appliance will operate continuously.

Mettre l'appareil inspecté en marche. Suivre les instructions d'allumage. Régler le thermostat de façon que l'appareil fonctionne de façon continue.
