CHAPTER 11 - START-UP PROCEDURES
11.3.5 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 11.3.4 on page 65.
2. Operate the unit for approximately 10 minutes.
3. Turn off all gas appliances within the building, ex-
cept the INSTINCT.
4. At the gas meter, record the time required to use
one cubic f oot 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. 26 on page 43.
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.
3. Touch the soft key while CH & DHW Settings
icon is highlighted.
4. Touch the soft key to highlight the Boiler Settings
icon then touch the soft key.
5. Touch the soft key to highlight Lockout
Temperature then touch the soft key.
6. Touch the soft key to highlight 102ºF [39ºC] then
touch the soft key.
7. Touch the soft key to highlight the Home Screen
icon
then touch the soft key.
8. Initiate a CH or DHW call and confirm that a High
Boiler Temperature lockout occurs once the supply
temperature reaches 102ºF [39ºC].
9. Touchany ARROW soft key to return to the Home Screen.
10. Touch simultaneously on the and soft keys for
3 seconds to access the functions for the installer.
11. Touch the soft key while the CH & DHW Settings

12. Touch the soft key to highlight the Boiler Settings
icon then touch the soft key.
13. Touch the soft key to highlight Lockout
Temperature, then touch the soft key.
14. Touch the soft key to highlight 210ºF [99ºC] then
touch the
soft key.
15. Touch the soft key to highlight the Home Screen
icon then touch the soft key.
