2. For zoned systems, flush each zone separately through a purge valve. (If purge valves and isolation valves are
not already installed, install them to properly clean the system.)
3. Flush system until water runs clean and you are sure piping is free of sediment.
*NOTE: It is recommended you clean heat exchanger at least once a year to prevent lime scale buildup. Follow
the maintenance procedure to clean the heat exchanger in the Maintenance Section (Part 12 of this manual).
Test/replace freeze protection fluid
1. For systems using freeze protection fluids, follow fluid manufac
turer’s instructions to verify inhibitor level and
that other fluid characteristics are satisfactory.
2. Freeze protection fluid must be replaced periodically due to degradation of inhibitors over time. Follow all fluid
manufacturer instructions.
NOTE: BOILER FAILURE DUE TO IMPROPER WATER CHEMISTRY IS NOT COVERED BY WARRANTY.
B. CHECK FOR GAS LEAKS
Before starting the boiler, and during initial operation, smell near the floor and around the boiler for gas odorant or
any unusual odor. Remove boiler front door and smell interior of boiler enclosure. Do not proceed with startup if
there is any indication of a gas leak. Repair any leaks at once.
PROPANE BOILERS ONLY
– Your propane supplier mixes an odorant with the propane to make its presence
detectable. In some instances, the odorant can fade, and the gas may no longer have an odor. Before startup
(and periodically thereafter), have the propane supplier verify the correct odorant level in the gas.
C. FREEZE PROTECTION (WHEN USED)
NEVER use automotive or standard glycol antifreeze. Do not use ethylene glycol made for hydronic systems. Use
only freeze-protection fluids certified by fluid manufacturer as suitable for use with stainless steel boilers, verified
in the fluid manufacturer
’s literature. Thoroughly clean and flush any system that has used glycol before installing
the new boiler. Provide the boiler owner with a material safety data sheet (MSDS) on the fluid used.
1. Determine the freeze protection fluid quantity using total system water content following the fluid
manufacturer’s instructions. Remember to include expansion tank water content.
2. Local codes may require back flow preventer or actual disconnect from city water supply.
3. When using freeze protection fluid with automatic fill, install a water meter to monitor water makeup. Freeze
protection fluid may leak before the water begins to leak, causing concentration to drop, reducing the freeze
protection level.
D. FILL AND TEST WATER SYSTEM
Ensure the boiler is full of water before firing the burner. Failure to do so will damage the boiler. Such damage IS
NOT covered by warranty, and could result in property damage, severe personal injury, or death.
