11.3.6 Measure Input - Natural Gas Only
1. Ensure the boiler is ring at maximum ring rate. To
manually place the boiler into high re, reference
Section 11.3.5 on page 73.
2. Operate the unit for approximately 10 minutes.
3. Turn o all gas appliances within the building, ex-
cept the INSTINCT.
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 102º F [39ºC] for testing.
1. Touch simultaneously on the
and soft keys
for 3 seconds to access the functions for the install-
er. Reference Fig. 34 on page 51.
2. Enter the installer access code “054”, using the
and
soft keys to select a digit and the and
soft keys to change the digit. Touch the
soft key
to enter the access code.
