Start-up — overviewVIIa
❏ Determine if water treatment will be needed to compensate for water hardness or pH.
❏ Obtain propylene/glycol antifreeze if freeze protection is required. Glycol must be propylene
glycol only, and special requirements may apply when using glycol.
❏ Check for gas leaks (and verify propane odorant level).
❏ Fill system with water and purge air. Verify water piping is leak-free.
❏ Study boiler operating instructions, Section IX. Then start boiler.
❏ Verify water piping, gas piping and vent system are leak-free. Verify igniter operation.
❏ For installations at altitudes over 5,500 feet above sea level, measure gas valve outlet
pressure and adjust if required (see also Section IId).
Do not use petroleum-based
cleaning or sealing compounds
in boiler system. Severe damage to
boiler will occur, resulting in
substantial property damage.
Start-up — preparationVIIb
1. Determine antifreeze quantity according to system
water content. Boiler water content is listed in Table
12 on page 95. Remember to include expansion tank
water content.
2. Follow antifreeze manufacturer's instructions.
3. A 50% solution of propylene glycol/water provides
maximum protection to about -30 °F.
4. Local codes may require back flow preventer or
actual disconnect from city water supply.
5. When using antifreeze in a system with automatic
fill, install a water meter to monitor water makeup.
Glycol will leak first at any leak spot. Added water
will dilute the antifreeze, reducing the freeze protection
level.
Eliminate all system leaks. Continual
fresh makeup water will reduce boiler
life. Minerals can build up in sections,
reducing heat transfer, overheating
cast iron, and causing section failure.
Verify water chemistry
Consult local water treatment companies for unusually
hard water areas (above 7 grains hardness) or low pH
water conditions (below 7.0).
Freeze protection (when
used)
Use antifreeze made especially for hydronic systems.
Inhibited propylene glycol is recommended.
Do not use ethylene glycol,
automotive or undiluted
antifreeze
. Severe personal injury
or death can result.
