C. INSTALLATIONUSINGVENT EXTENSION TUBES
When it isnot possibleto install thefurnace as described in installationsA or
B.
exlension tubes must be usedtoconnectthe exhaust and intake tube to thevent
assembly on the outside of the coach.
Avoid the use of exlension tubes whenever
possible. If they must be used, it is
important that the correct length tubes are used.
Inordertodeterminethecorrect exlens~ontubekit,you must determinethe range
in which the exlension falls To do this, position the furnace in its permanent
locationand measurethe distancefrom the end of the exhaust and intaketubeto
the outer edge of the coach skin. This determines the exlension tube range you
need. Figure 4 listsby kit number the vent exlension range up to
