Start-up — preparation

Check for gas leaks
Before starting the boiler, and dur-
ing initial operation, smell near the
floor and around the boiler for gas
odorant  or  any  unusual  odor.  Do
not proceed with start-up if there is
any indication of a gas leak. Repair
any leak at once.
Propane boilers only
— Your pro-
pane 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.
•  Propane  gas  can  accumulate
at  floor  level.  Smell  near  the
floor for the gas odorant or any
unusual  odor.  If  you  suspect  a
leak, do not attempt to light the
pilot.
•  Use  caution  when  attempting
to  light  the  propane  pilot.  This
should  be  done  by  a  qualified
service  technician,  particularly
if pilot outages are common.
•  Periodically  check  the  odorant
level of your gas.
•  Inspect boiler and system at least
yearly to make sure all gas piping
is leak-tight.
•  Consult  your  propane  supplier
regarding  installation  of  a  gas
leak  detector.  There  are  some
products on the market intended
for  this  purpose. Your  supplier
may be able to suggest an appro-
priate device.
Determine if water treatment is needed
Do  not  use
petroleum-based  cleaning  or  sealing 
compounds
in boiler system. Severe damage to boiler
will occur, resulting in substantial property damage.
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  grains hardness) or low pH water conditions (below .0). Boiler
water pH of .0 to 8.5 is recommended.
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.
1.  Determine
antifreeze  quantity
  according  to  system  water  content.
Boiler water content is listed on page 6. Remember to include expan-
sion tank water content.
.  Follow antifreeze manufacturer’s instructions.
3.  A 50% solution of propylene glycol/water provides maximum protec-
tion 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  before  the  water
begins to leak, causing glycol level to drop. Added water will dilute the
antifreeze, reducing the freeze protection level.
