This appliance is a gas-fired direct vent hot water boiler with cast aluminum boiler sections. A revolutionary cast aluminum heat exchanger means better heat transfer and thermal storage than similarly sized cast iron boilers, which results in higher efficiency. The heating system water absorbs large amounts of heat from the cast aluminum heat exch[...]

BOILER RATINGS AND CAPACITIES 4 These low pressure gas-fired hot water boilers are design certified by CSA International for use with natural and propane gases. The boilers are constructed and hydrostatically tested for a maximum working pressure of 50 psig (pounds per square inch gage) in accordance with A.S.M.E. (American Society of Mechanical En[...]

5 U.S.A. ONLY: For altitudes above 2,000 feet above sea level, input ratings should be reduced as shown in tables IA, C, & E for natural gas boilers or in tables 1B, D & F for propane fired boilers. Reduced input ratings are achieved by the natural deration of the gas at higher elevations and fine tuned by adjusting the manifold pressure. C[...]

9 1. Select a location which is level, central to the piping systems served and as close to the vent and air intake terminals as possible. 2. Accessibility clearances, if more stringent (i.e. larger clearances) than required fire protection clearances, must be used for the boiler installation. Accessibility clearances may be achieved with the use o[...]

10 CAUTION KEEP BOILER AREA CLEAN OF DEBRIS AND FREE OF FLAMABLE AND COMBUSTIBLE MATERIALS, VAPORS AND LIQUIDS WARNING When vent pipe is exposed to temperatures below freezing, such as when it passes through an unheated space or when a chimney is used as a raceway, vent pipe must be insulated with 1/2 Armaflex or equivalent. In extreme cold clim[...]

11 NOTE: 1. If boiler is not level condensate drain lines will not function properly. Adjustable feet are located on the boiler to make up for minor surface irregularities or tilt. 2. Wood frame or blocks may be used to raise boiler to maintain drain pitch or to be above external condensate pump reservoir. H. REMOVAL OF EXISTING BOILER FROM COMMON [...]

12 CAUTION Copper supply and return piping. must NOT be installed directly into aluminum boiler section casings due to galvanic corrosion between dissimilar metals. Iron or steel bushings or pipe nipples should be used between copper system piping and boiler to make final connection to boiler. Also, the use of dielectric unions is acceptable. The p[...]

Disconnect the vent con[...]

In Canada construct all combustion air and vent pipes for this unit of CSA or ULC certified schedule-40 CPVC, schedule-40 PVC, PVC-DWV or ABS-DWV pipe and pipe cement. SDR pipe is NOT approved in Canada. 3. Combustion air and vent piping connections on boiler are sized for 2" pipe. Any pipe size change (to 3") must be made outside of the [...]

22 6. C o nsideration for the following should be used when determining an appropriate location for termination of combustion air and vent piping.  Comply with all clearances required as stated in paragraph 7.  Termination should be positioned where vent vapors will not damage plants/shrubs or air conditioning equipment.  Termination shoul[...]
