CHAPTER 11 - START-UP PROCEDURES
11.3.5 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 11.3.4 on page 73.
2. Operate the unit for approximately 10 minutes.
3. Turn o all gas appliances within the building, ex-
cept the EXALT.
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.
11.3.6 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
