smell, check that:

• The specified gas type is correct for the area.
• There are no breaks/escapes in gas supply.
• There is no air in the gas supply.
⇒
Check the gas pressure at both the meter and the
appliance.

Air in the gas line will prevent the appliance from
igniting.

When the room does not reach the selected temperature, or
the appliance will not remain alight, check that:
• The selected temperature is not set lower than the
room temperature.
⇒
Select the required temperature setting with the UP/
DOWN selection buttons.
3. Blocked air filter
If insufficient heating or lockout occurs, check that:
• The air filter is not blocked with dust.
⇒
If the air filter is blocked, the safety device will operate.
