OPINION
HOYT, Justice.This appeal is taken from a summary judgment entered in a wrongful death action brought on theories of negligence and strict product liability.
In June 1984, the appellant’s father, Albert Beans, purchased a home and requested that Entex, Inc.' (“Entex”), a supplier of natural gas, begin servicing his home with its gas. Entex complied, and gas service to Mr. Beans’ home was initiated. On the evening of November 29, 1984, Mr. Beans turned on an unvented gas-fired space heater and retired to bed. The next morning, he was found dead; the cause of death was determined to be asphyxiation due to carbon monoxide inhalation.
On November 15, 1985, the appellant commenced this wrongful death suit against Entex and Dover Corp., Inc., manufacturer of the heater, under theories of negligence and strict product liability, for defective design and manufacture, and for failure to warn of the unreasonably dangerous nature of their products.
Entex filed a motion for summary judgment, and after a hearing, summary judgment was granted for Entex. A final judgment and order of severance was signed on March 9, 1987, and this appeal was brought.
In three points of error, the appellant contends that the trial court erred in entering a summary judgment: (1) on the appellant’s claim of product liability; (2) on the appellant’s claim of negligence; and (3) on the appellee’s plea of limitation.
Where a movant has received a summary judgment in his favor, the question on appeal is not whether the summary judgment proof raises fact issues with reference to the essential elements of a plaintiff’s claim or cause of action, but rather whether the summary judgment proof establishes, as a matter of law, that there is no genuine issue of material fact as to one or more of the essential elements of the nonmovant’s cause of action. Gibbs v. General Motors Corp., 450 S.W.2d 827, 828 (Tex.1970). The burden of summary judgment proof is on the movant, and all reasonable doubts as to the existence of a genuine issue of material fact are resolved against him. Farley v. Prudential Ins. Co., 480 S.W.2d 176, 178 (Tex.1972).
The subject of product liability is addressed in Restatement (Second) of Torts § 402A (1965), which provides:
(1) One who sells any product in a defective condition unreasonably dangerous to the user or consumer or to his property is subject to liability for physical harm thereby caused to the ültimate user or consumer, or to his property, if
(a) The seller is engaged in the business of selling such a product, and
(b) it is expected to and does reach the user or consumer without substantial change in the condition in which it is sold.
This rule is not relaxed even though the seller exercises all possible care in the preparation and sale of the product. Id. at § 402A(2). Similarly, in common-law negligence cases, a plaintiff, to recover must establish a duty on the part of a defendant. Duff v. Yelin, 721 S.W.2d 365, 370 (Tex.App.—Houston [1st Dist.] 1986, writ pending).
The appellant contends that Entex’s failure to inspect Mr. Beans’ pipes and appli-*325anees, and to warn of the potentially life-threatening consequences of using an un-vented gas heater caused the gas sold by the appellee to be “defective” and unreasonably dangerous.
A product cannot be said to be unreasonably dangerous because of a failure to warn, unless there is a duty to warn. Houston Lighting & Power Co. v. Reynolds, 712 S,W.2d 761, 767 (Tex.App.—Houston [1st Dist.] 1986, writ granted). The seller’s duty to warn arises only where the dangers to be warned of are reasonably foreseeable and are such that a consumer cannot reasonably be expected to be aware of them. Id.
The evidence in the summary judgment proof shows that the cause of Mr. Beans’ death was due to a faultily adjusted or vented gas heater and not the product (natural gas). A duty on the part of Entex to warn that asphyxiation could, result from a faultily adjusted gas heater or to inspect every pipe and appliance in every establishment serviced would require Entex to take responsibility for property that it does not own or control. See Lane v. Community Natural Gas Co., 133 Tex. 128, 123 S.W.2d 639 (1939). There is nothing in our record to indicate that the deceased or any other person requested En-tex to inspect the gas appliances at the deceased’s residence. We conclude that Mr. Beans was responsible for the maintenance and upkeep of his heater and that, absent any proof that the gas supplied caused the defect in the appliance, or that the gas was otherwise in a defective condition such as would prevent it from being used for its intended purpose, it is not reasonably foreseeable that a consumer would attempt to operate a gas appliance without first obtaining a maintenance check on the appliance. See Houston Lighting & Power Co., 712 S.W.2d at 767. Asphyxiation, due to carbon monoxide inhalation from unvented gas heating, is of such common propensity as to be an open and obvious danger.
Because the summary judgment proof establishes, as a matter of law, the absence of an essential element of the appellant’s cause of action, i.e., the duty to inspect and warn, the summary judgment was proper. Sakowitz v. Steck, 669 S.W.2d 105 (Tex.1984). Additionally, the appellant has failed to establish any common-law duty to warn.
The appellant’s first and second points of error are overruled.
In view of our disposition of the appellant’s first and second points of error, it is unnecessary to address her third point of error.
The judgment of the trial court is affirmed.
