Table 2 Manifold orifi ce sizing
Inspect orifi ces and burners
1. Remove front jacket door. Remove inlet air box top
panel (see Figure 27, item 13, page 56).
2. Check for correctly-sized manifold orifi ces. See
Table 2 for sizing. (The orifi ce size is stamped on
the orifi ce spud barrel.)
Correctly-sized manifold orifices
must be used. Failure to do so will
result in severe personal injury,

orifi ces from the manifold.

correctly, not cross-threaded in the manifold tap-

Use only pipe dope compatible with
propane gas, even if boiler is to be
operated on natural gas. Failure to
comply could result in severe per-

property damage.
