Making boiler ready for operation

STOP! First read the safety instructions on Î page 8 of
this manual.
1. Carry out leak test (Î page 7). Wait five (5) minutes
until all gas residues have dissipated. Finally check
whether there is any smell of gas, including at floor
level. If there is a gas odor: STOP! Follow
instructions in section "B" of the safety instructions
on Î page 8 of this manual. If there is no sign of a
gas odor, continue with the next step.
2. Open main gas valve.
4.1.1 Placing heating system with aquastat control in operation
The boiler is fully functional with the factory-installed
aquastat.
3. Switch on ON/OFF switch (building side)
(ON position). This switches on the boiler with all its
components. Then continue with step 7.
4. Make sure that the room thermostat signals a heat
requirement (set thermostat at least 10 °F above
room temperature).
We reserve the right to make any changes due to technical modifications.
