NATION LOCATIONS Follow these guidelines for locating the vent air terminations 1 Make sure the total length of piping for vent or air do not exceed the limits mentioned in Table 13 and Table 14 on Page 37 2 Consider the surroundings when terminating the vent and air While positioning the vent termination ensure vapors will not damage nearby shrubs plants or air conditioning equipment The flue products will form a noticeable plume as they condense in cold air Avoid areas where the plume could obstruct window views Prevailing winds could cause freezing of condensate and water ice buildup where flue products impinge on building surfaces or plants Do not allow accidental contact of flue products with people or pets Do notlocate the terminations near building corners near adjacent buildings or surfaces window wells stairwells alcoves courtyards or other recessed areas where wind eddies could affect performance or cause recirculation Sidewall vent and air inlet terminations must terminate the same pressure zone Do not terminate above any door or window where condensate can freeze causing ice formations Locate or monitor the vent to prevent condensate damage to exterior finishes 3 The air piping must terminate in a down turned elbow using a mesh screen This setup will avoid recirculation of flue products into the combustion air stream See Figure 32 4 The vent piping must term
274. NNECTIONS A CAUTION The gas type must match the gas type on the rating plate Gas supply pressure must match pressure indicated on the rating plate Isolate boiler from gas supply piping system Disconnect boiler and main manual gas shutoff valve from gas supply during pressure testing of gas supply system Make sure the gas on which boiler is to operate is same as that specified on the rating plate Do not install boiler if equipped for a different type of gas Consult your gas supplier This boiler is not intended to operate at gas supply pressure other than shown on the rating plate A lock up or positive shut off type regulator must be installed in gas supply line For proper gas regulation the lock up style regulators must be installed no closer than a minimum of 3 feet 0 9 m from the boiler and a maximum of 8 feet 2 4 m away from the boiler Exposure to higher gas supply pressure may cause damage to gas control valves which can result in fire or explosion If overpressure has occurred such as through improper testing of gas lines or emergency malfunction of supply system the gas control valves must be checked for safe operation Make sure that the outside vents on supply regulators and the safety vent valves are protected against blockage These are parts of the gas supply system not boiler Vent blockage may occur during ice build up or snowstorms The boiler must be isolated from the gas supply piping system by
