INNER FLUE
This flue kit has been manufactured for use with GF900L and to be installed
in accordance with AS/NZS 5601-2013. To ensure safety and correct unit
operation this flue kit must be installed as outlined in these instructions. Heater
and flue clearances from combustible materials must be in accordance with
these instructions and AS/NZS 5601-2013.
1. Locate the heater in its proposed position and mark the point for penetra-
tion directly above the centre of the heater flue outlet. Check the heater
location allows the outer flue to clear all structural timber and combustible
surfaces as per the manual.
2. If the enclosure consists of a ceiling – cut a 255mm square hole (minimum)
for the flue to penetrate, cut hole through roofing material and prepare
flashing for termination.
3. Starting at the heater, install first length of inner pipe, crimped end down,
using Mill-Pac sealant and self-tapping screws (or rivets). Note – first
length of inner pipe has a swage only.
4. Continue assembling flue pipes inner and outer, ensuring each inner
join is sealed using Mill-Pac sealant and self-tapping screws (or rivets).
Outer flue pipe is to be installed with crimped end up then sealed and
fixed together also.
5. If required, fix outer flue in the ceiling space using non-combustible brac-
ing to stop movement. On penetration of roof, fit an appropriate flashing
or weather seal to suit the roofing material, ensure all joints outside are
sealed with appropriate sealer.
6. Fit gas cowl (46DVA-VCH/9) or flomet cap (946-651) ensuring inner and
outer flue pipes are sealed.
7. Start heater and run for at least 15 minutes to check flue seal. If operational
issues are noted, check flue again to ensure proper seal of inner pipe.
