i. Assure that all system radiators, piping and vents are absolutely leak tight. • When a steam boiler is installed in an existing system, ALL air vents should be replaced at the same time. This assures that the new boiler will not be compromised by existing system leaks. • If the system contains hidden supply or return piping (hidden behind walls, buried in concrete, etc.) pressure test this piping to assure there are no leaks. ii. Repair any leaks in the system. iii. Install accurate water met

Refer to Table 9 for proper nozzle size, air settings and fuel pump pressure setting based on desired firing rate. If the desired firing rate is the lower GPH: a. replace the factory installed high firing rate nozzle with one of the loose lower firing rate nozzles. b. replace the factory installed head positioning bar with the corresponding head bar that matches the lower GPH nozzle installed, see Table 9. c. change the factory air settings according to Table 9 and, d. check the oil pump pressur

Example: For an energy consumption of 21,500 MJ per year and a natural gas tariff of 2.1 cents per MJ ($0.021/MJ), the lifetime running cost is: 21,500 x $0.021 x 12 = $5,418 The labels can also be used to estimate the lifetime greenhouse gas emissions. For each MJ of gas consumed, around 0.06 kg of carbon dioxide is emitted, so for the example above the greenhouse gas emissions are: 21,500 x 0.06 x 12 = 15,480 kg or 15.48 tonnes The actual running costs and greenhouse gas emissions will depend
