<br />CHAPTER 91. HEATING APPLIANCES AND SYSTEMS.
<br />1591.01 Scope and application.
<br />The provisions of this chapter shall govern
<br />the installation, alteration, replacement and
<br />repair of heating systems. When alterations
<br />are made to existing systems, the provisions
<br />of this Dwelling House Code shall apply to
<br />the new work and material,
<br />1591.02 Qualified 'installers.
<br />All heating installations and alterations
<br />shall be done by or under the direct super-
<br />vision of installers registered or authorized
<br />to do such work under the applicable pro-
<br />visions of Chapter 15.
<br />1591.03 Permits.
<br />No work, other than minor repairs as de-
<br />fined in Section 1517.14, shall be done on any
<br />heating system without first procuring a per-
<br />mit for the work. Said permit may include
<br />only such piping and electric wiring as, in
<br />the opinion of the Building Official, are nor-
<br />mally included in and essential to the in-
<br />stallation of the heating equipment.
<br />1591.04 Drawings, layouts and design data.
<br />Before a permit is issued for the installa-
<br />tion or alteration of any heating system, the
<br />applicant shall submit drawings, layouts and
<br />design data to the Building Official showing
<br />the proposed installation or alteration and
<br />indicating the size, type, capacity and loca-
<br />tion of all equipment.
<br />1591,05 Required capacity of heating
<br />equipment.
<br />(a) Interior temperature requirements.
<br />Except for panel heating, and as provided in
<br />subsection (b) of this Section; heating equip-
<br />ment shall be adequate to maintain an in-
<br />terior temperature of not less than 70 F in all
<br />spaces customarily used for human occu-
<br />pancy when the outdoor temperature is -5 F
<br />and the wind velocity is 15 miles per hour,
<br />without forcing the equipment beyond the
<br />rated capacity of the burner, boiler or fur-
<br />nace. A panel heating system shall be ade-
<br />quate to maintain an interior temperature of
<br />not less than 68 F under the aforementioned
<br />conditions. The required temperatures shall
<br />not apply in play rooms, laundry rooms and
<br />other spaces not customarily used for human
<br />occupancy.
<br />(b) New installations in existing dwell-
<br />ings. When new heating installations are
<br />made in existing dwellings which have been
<br />erected prior to the effective date of this
<br />Dwelling House Code and strict conformity
<br />with the provisions of subsections (a) and
<br />(d) of this section would result in undue
<br />hardship, the Board of Building Code Ap-
<br />peals may approve installations which will
<br />not provide the prescribed interior tempera-
<br />ture, provided such installations are made
<br />with the prior knowledge and written con-
<br />sent of the owner and no hazard to fire or life
<br />is created thereby.
<br />(c) Acceptable engineering practice.
<br />Where the quality of materials or the safe
<br />capacity of a heat appliance, device or equip-
<br />ment is not established by this Dwelling
<br />House Code or defined or established by the
<br />Board of Building Code Appeals, the pub-
<br />lished recommendations and data of the
<br />following organizations, identified in Chapter
<br />21, may be accepted by the Building Official
<br />as defining accepted safe engineering prac-
<br />tice, provided, however, that the Board of
<br />Building Code Appeals may change, modify,
<br />or. supplement any of the requirements of
<br />such recommendations when deemed neces-
<br />sary in the interest of public safety or to
<br />further define accepted safe practice:
