HTP ELP-199 - Manual (Page 51)

LP-294 REV. 2.20.14
NEVER use automotive or standard glycol antifreeze. Do not use ethylene glycol made for hydronic systems. Use only generally
recognized as safe freeze prevention fluids certified by fluid manufacturer as suitable for use with stainless steel boilers, verified in the
fluid manufacturer literature.
Thoroughly clean and flush any system that has used glycol before installing the new boiler. Provide the owner with a Material Safety
Data Sheet (MSDS) on the fluid used.
2. Local codes may require a 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.
C. 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.
1. Fill the system only after ensuring the water meets the requirements of this manual.
2. Close the manual and automatic air vents and boiler drain valve.
3. Fill to the correct system pressure. Correct pressure will vary with each application.
a. Typical cold water fill pressure for a residential system is 12 psi.
b. Pressure will rise when boiler is turned on and system water temperature increases. Operating pressure must never exceed
the relief valve pressure setting.
4. At initial fill and during boiler startup and testing, check system thoroughly for any leaks. Repair all leaks before proceeding further.
5. Run pumps in System Test. Check for leaks.
Eliminate all system leaks. Continual fresh make-up water will reduce boiler life. Minerals can build up in the heat exchanger, reducing
heat transfer, overheating the heat exchanger, and causing heat exchanger failure.
6. The system may have residual substances that could affect water chemistry. After the system has been filled and leak tested, verify
that water pH and chlorine concentrations are acceptable by sample testing.
It is important that you purge the system of air to avoid damage to the boiler.
D. 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 USE 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.
NOTE: When checking for gas leaks with leakage spray, use only approved chloride free leakage sprays. Use of chloride leakage
sprays will result in damage to the boiler. Such damage is not covered by warranty.
