11.3.6 Measure Input - Natural Gas Only

1. Ensure the boiler is firing at maximum firing rate. To
manually place the boiler into high fire, reference
Section 11.3.5 on page 56.
2. Operate the unit for approximately 10 minutes.
3. Turn off all gas appliances within the building, ex-
cept the PRESTIGE Excellence.
4. At the gas meter, record the time required to use
one cubic foot of gas.
5. Calculate Natural gas input using the following
equation:
3600 x 1000 / number of seconds recorded for one
cubic foot of gas = BTU/H.
6. The BTU/H calculated should approximate the in-
put rating listed on the unit.

11.3.7 Test High Temperature Limit

The high temperature limit can be temporarily lowered
from 210ºF [99ºC] to 102ºF [39ºC] for testing.
