SECTION 3: CLEARANCES TO COMBUSTIBLES
3.1 Re q uired Clearances to Combustibles
Clearances are the req u ired distances that
comb u stible objects m u st be a w ay from the heater to
pre v ent serio u s fire hazards. Comb u stibles are
materials, that may catch on fire and incl u de common
items s u ch as w ood, paper, r u bber, fabric, etc.
Maintain clearances to combustibles at all times
for safety.
Clearances for all heater models are located on the
b
u rner of the heater and on Page 6, Figure 3 through
Page 8, Figure 9 in this man u al. Check the
clearances on each b u rner for the model heater
being installed to make s u re the prod u ct is s u itable
for yo u r application and the clearances are
maintained. Read and follo w the safety g u idelines
belo w :
• Keep gasoline or other comb u stible materials
incl u ding flammable objects, liq u ids, d u st or
v apors a w ay from this heater or any other
appliance
• The stated clearance to comb u stible represents a
s u rface temperat u re of 90° F (50°C) abo v e room
temperat u re. B u ilding materials w ith a lo w heat
tolerance (s u ch as plastics, v inyl siding, can-
v as,triply, etc.) may be s u bject to degradation at
lo w er temperat u res. It is the installer’s responsibil-
ity to ass u re that adjacent materials are protected
from degradation.
• Maintain clearances from heat sensiti v e
eq u ipment and w orkstations.
• Maintain clearances from v ehicles parked belo w

• Maintain clearances from s w inging and o v erhead
doors, o v erhead cranes, v ehicle lifts, partitions,
storage racks, hoists, b u ilding constr u ction, etc.
• In locations u sed for the storage of comb u stible
materials, signs m u st be posted to specify the
maxim u m permissible stacking height to maintain
req u ired clearances from the heater to the
comb u stibles. Signs m u st be posted adjacent to
the heater thermostat. In the absence of a
thermostat, signs m
u st be posted in a
conspic u o u s location.
• Cons u lt local Fire Marshal, Fire Ins u rance Carrier
or other a u thorities for appro v al of proposed
installation w hen there is a possibility of expos u re
to comb u stible airborne materials or v apors.
• Hang heater in accordance to the minim u m s u s-
pension req u irements on Page 13, Figure 11 .
• If the radiant t u bes m u st pass thro u gh the b u ilding
str u ct u re, be s u re that adeq u ate slee v ing and fire
stop is installed to pre v ent scorching and/or fire
hazard.
NOTE: 1. All dimensions are from the s u rfaces of all t u bes, co u plings and elbo w s.
2. Clearances B, C and D can be red u ced by 50% after 25' (7.5 m) of t u bing do w nstream
from w here the b u rner and b u rner t u be connect.
