SECTION 3: CRITICAL CONSIDERATIONS
3.1 Re q uired Clearances to Combustibles
Clearances are the req u ired distances that
com bu sti b le o b jects m u st b e a w ay from the air
t u rno v er u nit to pre v ent fire hazards. Com bu sti b les
are materials that may catch on fire and incl u de
common items s u ch as w ood, paper, r ubb er, fa b ric,
etc. Maintain clearances to combustibles at all
times for safety.
Check the clearances on each air t u rno v er u nit b eing
installed to make s u re the prod u ct is s u ita b le for yo u r
application and the clearances are maintained.
Minim u m clearances for all models are as follo w s:
• 18" (45.7 cm) A b o v e the top of the eq u ipment
• 18" (45.7 cm) Along the sides of the eq u ipment
• 36" (91.4 cm) Aro u nd the fl u e pipe
• 36" (91.4 cm) Aro u nd the sight port
Read and follo w the safety g u idelines b elo w :
• Locate the air t u rno v er u nit so that the air intakes
are not too close to any exha u st fan o u tlets,
gasoline storage, propane tanks or other
contaminants that co
u ld potentially ca u se
dangero u s sit u ations.
• Keep gasolines or other com bu sti b le materials
incl u ding flamma b le o b jects, liq u ids, d u st or
v apors a w ay from this air t u rno v er u nit or any
other appliance.
• Maintain clearances from heat sensiti v e material,
eq u ipment and w orkstations.
Clearances to com bu sti b les do not denote
clearances for accessi b ility. Minim u m clearance for
access is 48" (122 cm). Minim u m clearance for
accessi b ility applies to the control enclos u re, and
inlet plen u m access panel.
The stated clearances to com bu sti b les represent a
s u rface temperat u re of 90° F (32° C) a b o v e room
temperat u re. B u ilding materials w ith a lo w heat
tolerance (i.e. plastics, v inyl siding, can v as, tri-ply,
etc.) may b e s ub ject to degradation at lo w er
temperat u res. It is the installer’s responsi b ility to
ass u re that adjacent materials are protected from
degradation. Maintain clearances from heat sensiti v e
material, eq u ipment and w orkstations.
