9.3 Service connections
1. Connect the central heating circuit to the top of the appliance using 22 mm compression fittings to avoid heat damage to the case and seals; the return is on the left and
the flow is on the right.
NOTE: To assist with the purging of air from the system pour water into the flow
and return connections to displace the air in the heat exchangers.
2. Connect the gas to the bottom right of the appliance using the 15 mm gas cock provided (in the top of the packaging). Remove the bottom cover and lower the control tray
(See Section 10.1 paragraph 3 and Figs. 40 and 41). Install with the test nipple to the left (see Fig. 11) this allows the connection to the appliance to be tightness tested
independently of the gas pipework up to the appliance which then can be tested using the test nipple on the gas meter. It may be difficult to reassemble the bottom panel if
this is not done.
3. Note: Care must be taken to ensure that the over current switch is not disturbed from its correct position (See Fig. 2a when replacing the bottom cover). The switch should
be up at the back ­ the '1' should be depressed.
9.4 Condensate Drain ­ see section 7.8
1. Connect the condensate drain to the trap outlet pipe.
