FLUEING ARRANGEMENTS - HORIZONTAL TERMINATIONS
MASPORT CO AXIAL FLUE SYSTEM (FLEX)
(Propane & Natural Gas)
The diagram below shows examples of horizontal termination arrangements using two 90
o
elbows (two 45
o
elbows
equal one 90
o
elbow).
Note: 1) A maximum of two 90
o
elbows are permitted.
2) A minimum of 1.8m vertical from base of unit is required if two 90
o
elbows are used.
3) Minimum distance between elbows is 600mm.
4) Determine the permitted range of horizontal termination arrangements by using chart on page
12 and deducting 1 metre from the maximum horizontal distance for the second 90
o
elbow.
• Maintain clearances to combustibles.
• Horizontal flue must be supported every 1 metre.
A flue guard should be used
whenever the termination is lower
than the specified minimum or as
per local codes.
If length "B" is increased, length
"A" must be decreased by a
corresponding amount.
